Abstract
Purpose
Indicators of socioeconomic status (SES), such as education and occupational grade, are known to be associated with alcohol use but this has not been examined among individuals with a mental health problem. This study developed latent classes of SES, their associations with alcohol use, and examined the indirect effect via social support and neighbourhood environment.
Methods
A secondary analysis of the 2014 Adult Psychiatric Morbidity Survey was conducted among participants with a mental health problem (N = 1,436). SES classes were determined using a range of indicators. Alcohol use was measured using the Alcohol Use Disorder Identification Test. Social support and neighbourhood neighbourhood environment were measured using validated questionnaires. A latent class analysis was conducted to develop SES classes. Multinomial logistic regression examined associations of SES and alcohol use. Structural equation models tested indirect effects via social support and neighbourhood environment.
Results
A four-class model of SES was best-fitting; “economically inactive,GCSE-level and lower educated,social renters”, “intermediate/routine occupation,GCSE-level educated,mixed owner/renters”, “retired, no formal education,homeowners”, and “professional occupation,degree-level educated,homeowners”. Compared to “professional occupation,degree-level educated, homeowners”, SES classes were more likely to be non-drinkers; odds were highest for “economically inactive,GCSE-level and lower educated,social renters” (OR = 4.96,95%CI 3.10–7.93). “Retired, no formal education,homeowners” were less likely to be hazardous drinkers (OR = 0.35,95%CI 0.20–0.59). Associations between “economically inactive,GCSE-level and lower educated,social renters” and “retired, no formal education,homeowners” and non- and harmful drinking via social support and neighbourhood environment were significant.
Conclusions
In contrast to the alcohol harms paradox, among individuals with a mental health problem, lower SES groups were more likely to be non-drinkers while no associations with harmful drinking were found. There is also a need to examine the alcohol harms paradox in the context of the area in which they live.

Introduction
Background
The global prevalence of past year alcohol use is 52.3%, while the prevalence of alcohol use disorder (AUD) is around 2.2% [1]. Alcohol is the most harmful drug when considering its impact on the individual and others [2]. Recent evidence has shown that the prevalence of AUD was higher among individuals meeting criteria for a mental health problem [3, 4], while mental health problems and AUDs contribute significantly towards disability-adjusted life years [5, 6] and mortality [7, 8].
The alcohol harms paradox [9] and social causation hypothesis [10, 11] suggest that individuals may be at greater risk of experiencing alcohol harms and reporting poorer mental health because of their socioeconomic status (SES). Previous research has shown that those of lower SES were more likely to experience alcohol harms, despite lower self-reported alcohol use [12,13,14]. Those from lower SES groups were also more likely to experience worsened mental health which may be explained by patterns of drinking [9, 12], other unhealthy behaviours [9], co-occurring health problems [9], and barriers to accessing services [9, 15]. A recent study also found that SES partially accounted for associations between alcohol use (including non-drinking), and mental health [16], suggesting that SES plays a role in this co-occurrence. However, SES is a multidimensional construct which comprises of different factors including economical resources and means, educational level, and occupation [17, 18], and previous research have used single measures of SES to examine associations with alcohol use [12] but these findings may differ depending on the measure of SES [13].
Latent class analysis (LCA) may be more appropriate because multiple measures of SES can be used to group individuals based on responding to different measures in a similar way. A previous study undertook a LCA which found that economically inactive (defined as being in receipt of benefits, being a renter, and having low education levels) groups were more likely to report harmful drinking; and having a common mental disorder (CMD) partially explained these increased associations in the general population [19]. Exploring SES in this way allows the researcher to examine the effect of having multiple advantages or disadvantages. Further, associations between SES and alcohol use may be stronger among individuals with poor mental health because they may experience multiple disadvantages.
There are also contextual factors which contribute towards the association between SES and different patterns of alcohol use among individuals who are experiencing mental health problems [16]. One factor is social support which can be defined by the social networks an individual has or by the type of support individuals receive from others which may come in the form of emotional (e.g. feeling loved), informational (e.g. providing information) or instrumental (e.g. tangible help) support [20]. The relationship between SES and social support is complex and its mechanisms are not well understood. It could be argued that individuals from lower SES backgrounds have more structural barriers and less opportunities to create a good level of social support [21, 22], for example, those from lower SES backgrounds may have less access to resources which could have a subsequent impact on accessing support, as such this could have an impact on health behaviours and outcomes. It could also be argued that social support acts as a buffer against stress and negative events [23]. Nonetheless, research has shown that social support can help to adjust to stressful conditions [24], while emotional support reduces the risk of a CMD [25]. The evidence on social support and drinking at harmful levels in the general population is mixed [26,27,28], but evidence suggests that social support can be particularly useful in maintaining non-drinking, particularly among those who have previously drank at harmful levels [29, 30]. However, despite research illustrating the associations between mental health and alcohol use [4, 16], there is seldom research which has explored the indirect role of social support on alcohol use among those with a mental health problem. Social support may be particularly beneficial for those with a mental health problem because of the additional stressors they may experience, however, to the author’s knowledge, this has not been explored. It could be argued that individuals from lower SES backgrounds with a mental health problem have less opportunities to create good quality social support, therefore have less recourses to cope and are more likely to use alcohol at harmful levels. This may explain previous research which has found associations between lower SES and harmful drinking after accounting for a CMD [19].
Another factor is the neighbourhood environment which is defined as the sense of belonging in the community, the presentation of surroundings, and the extent to which a person feels safe [31, 32]. Neighbourhood environment has been found to mediate relationships between SES with alcohol use [33,34,35] and mental health [31]. In the context of this study, it could be argued that individuals from higher SES backgrounds can afford to live in more advantaged areas where there is better access to mental health support and so alcohol may be used less to cope as indicated by the fundamental cause theory [36]. But little is known about how neighbourhood environment plays a role in the relationship between SES and alcohol use among individuals with a mental health problem.
This study aimed to address the following objectives among people meeting criteria for a mental health problem: i) understand how individuals are clustered based upon multiple indicators of SES to define latent classes, ii) determine associations between SES classes and alcohol use, and iii) examine whether there is an indirect effect of SES and alcohol use via social support and neighbourhood environment. We hypothesise that more advantaged SES classes will have increased odds of non-drinking or hazardous use and more disadvantaged classes will have increased odds of being a harmful/probable dependence. We also hypothesise that there will be an indirect association between more advantaged SES classes and non-drinking via increased social support and living in a better neighbourhood environment. Further, we hypothesise that there will be an indirect association between lower SES classes and harmful/probable dependence via decreased social support and living in a worse neighbourhood environment.
Methods
Study design
This study used data from the 2014 Adult Psychiatric Morbidity Survey (APMS) which uses a stratified multi-stage random probability sample. It is a cross-sectional survey of private households in England which has been on-going since 1993, with 2014 being the latest survey. 2014 APMS data was accessed through NHS Digital (ref. DARS-NIC-220105-B3Z3S-v0.3). We pre-registered our hypotheses and analyses (https://osf.io/h3ntf/).
Participants and setting
A detailed description of the APMS methodology is described elsewhere [37]. One adult aged 16 or older was selected from each eligible household to take part in a face-to-face interview and reimbursed with a £15 high street voucher. Interviews were conducted in individuals’ homes and some information was collected by self-completion using computer-assisted interviewing. Interviews were conducted from May 2014 to September 2015 [37]. This study focused on those meeting criteria for a mental health problem which ranged from depression to probable psychotic disorder, further detail around the specific types of mental health problems included, measures and cut-offs used can be found in Table S1 and elsewhere [16].
Measures
Given the multidimensional nature of SES, the following indices were used to measure SES within this study, each measure captures a different aspect of SES:
Social occupational grade: This variable was derived by combining responses from open questions on topics of the nature of the participants’ sector/industry, level of supervisory and managerial responsibilities as well as responses from the following items; ever having a job (“Have you ever had a paid job, apart from casual or holiday work?”) and reasons for not being in work (“What was the main reason you did not seek any work in the last 4 weeks/would not be able to start in the next 2 weeks?”). This variable was categorised as; i) managerial/professional, ii) intermediate, small employers and own account workers, iii) lower supervisory/technical/semi-routine/routine, iv) student, v) retired, and vi) never worked/not worked in the past year/not classified for other reason.
In debt: This variable was derived from item “Have there been times during the past year when you or your household were seriously behind in paying within the time allowed for any of these items?” and dichotomised as “yes” or “no”.
In receipt of any out of work benefits: This variable was derived from items “Are you currently receiving any of these benefits as the named recipient?” and "Are you currently receiving any of these benefits either as the named recipient, or on behalf of someone in your household" and dichotomised as “yes” or “no”.
Highest education qualification This variable was derived from item (“Please look at this card and tell me whether you have passed any of the qualifications listed. Look down the list and tell me the first one you come to that you have passed.”) and categorised as; i) University degree or higher, ii) A-Level/GCSE level, iii) other qualifications (including foreign qualifications), and iv) no qualifications.
Housing tenure:This variable was derived from two questions; “In which of these ways do you (or your household) occupy this accommodation?” and “Who is your landlord?”. Participants were categorised as; i) homeowner, ii) social renter, and iii) private renter.
Household type: Participants were asked to indicate their current household living situation and categorised as; i) lives alone, without children (reference), ii) lives with another adult without children, iii) lives in a family, and iv) lives in an adult household.
Alcohol use: Alcohol use was measured using two screening questions and participants’ scores on the Alcohol Use Disorder Identification Test (AUDIT); “Do you ever drink alcohol nowadays?”, those who responded “no” were then asked, “Could I just check, does that mean you never have an alcohol drink nowadays, or do you have an alcoholic drink very occasionally?”. Those who responded “no” did not complete the AUDIT. The AUDIT is a 10-item screen for alcohol use and related problems which has a maximum score of 40 [38], and good internal reliability within this sample (Cronbach’s α = 0.96). This tool has also been shown to have good validity [39]. Participants were categorised in accordance with established cut-offs [38]; “non-drinker” (answering “no” to screening questions or having an AUDIT score of 0), “low-risk” (AUDIT score:1–7, reference), “hazardous use” (AUDIT score:8–15), and “harmful/probable dependence” (AUDIT score:16 or above).
Social support: Perceived social support was measured using a seven-item questionnaire from the 1987 Health and Lifestyle Survey and has a maximum score of 21 [40]. The questionnaire is publicly accessible [41] and includes statements that individuals responded to as “not true”, “partly true”, or “certainly true” of their family and friends. These statements include the extent to which the participant believes that their friends and family i) do things to make them happy, ii) make them feel loved, iii) can be relied upon, iv) ensure that they would be taken care of, v) accept them as they are, vi) make them feel important, vii) give them support and encouragement. This measure has good internal reliability (Cronbach’s α = 0.94) and its validity has been established elsewhere [42, 43]. This measure was treated as a continuous variable, with a high score indicating strong social support.
Neighbourhood environmen:t Neighbourhood environment was measured using a 10-item questionnaire which asks participants questions around social cohesion [44] and neighbourhood quality [45]. All items except one (“The area is kept nice by its residents”) had good item-test correlation with the proposed constructs (Cronbach’s inter-item test correlation = 0.73–0.89). The item with lower item-test correlation compared to other items in the questionnaire (Cronbach’s inter-item test correlation = 0.42) was removed from analysis, thus, a nine-item questionnaire was used to generate a total score (Cronbach’s α = 0.84, RMSEA = 0.07, CFI = 0.98) with a maximum score of 45. This measure was treated as a continuous variable, with a high score indicating worse neighbourhood environment.
Sample size
The full sample size of the 2014 APMS was 7546, but after restricting to those individuals who met criteria for a mental health problem, the final sample was 1436.
Statistical analysis
Data was processed in STATA version 16 and analysed in MPlus version 8. A previous study using this dataset reported that most variables assessing specific types of mental health problems had a small amount of missing data (~ 0.01%) though alcohol use had 3.7% of missing data [16]. There was also a small amount of missing data for SES measures, social support and neighbourhood environment (1.03–1.64%). Of those included in the survey (N = 1,463), 27 (2.51%) did not complete the alcohol measures, therefore, a case-complete analysis was conducted. Potential non-response could be due to items being in the self-completion section of the questionnaire [37]. The analysis took part in three stages (see Fig. 1):
Indirect effects of social support and neighbourhood environment were calculated using the “MODEL CONSTRAINT” command where the path from each SES class to social support or neighbourhood environment were multiplied with the paths from social support or neighbourhood environment to each alcohol use category [46]). This allowed us to understand whether the indirect effect of social support and neighbourhood environment partially or fully accounted for the association between each SES class and alcohol use outcome [47]. Regression coefficients for indirect paths with continuous outcomes (social support and neighbourhood environment) were unstandardized and calculated using the Delta method [48]. Multinomial logistic regression coefficients for indirect paths with categorical outcomes (non-drinking, hazardous drinking, and harmful/probable dependence) were reported. To enable comparisons between the associations between each SES class and alcohol use outcomes, the exponentiated multinomial logit coefficients are reported in the figures. Due to the dependent variable being nominal, it was not possible to use additional model fit indices to assess the indirect associations of SES and alcohol use.
Multinomial logistic regression was used to calculate the paths from SES to alcohol use, and paths from social support and neighbourhood environment to alcohol use, respectively. For the multinomial logistic regressions in these models, the multinomial odds ratio, confidence intervals not overlapping with 1 and a p-value of less than 0.05 was deemed statistically significant. All analyses were conducted in MPlus version 8 and weighted to account for selection probabilities and non-response.
Sensitivity analysis
A sensitivity analysis of the prevalence of SES classes among individuals who met criteria for a CMD (defined as depressive and anxiety disorders [49]) or severe mental illness (SMI; defined as bipolar disorder, probable psychotic disorder and any other psychotic disorder [50]) was conducted. Household income was added to the latent class model as part of an additional sensitivity analysis. Household income was a categorical variable (less than £12,999, more than or equal to £12,999 or less than £20,279, more than or equal to £20,279 or less than £31,666, more than or equal to £31,666 or less than £52,499, more than or equal to £52,499) and there was 20.98% of missing data for this variable. Values were imputed through multiple imputation by chained equations [51] in STATA version 16. The imputation model included all of the SES variables used in the final latent class analysis (social occupational grade, being in debt, being in receipt of any out of work benefits, educational attainment, housing tenure and household type) and alcohol use were included in the imputation model which is considered as best practice for multiple imputation [52]. Ten cycles of the imputations were run. Once data was imputed, data were re-analysed as per steps outlined above. Analyses using the imputed and non-imputed data showed similar results, therefore, non-imputed data are shown in the results tables (see Table 2 and 3) while imputed data are shown in supplementary (see Tables s6-s10).
Results
Latent class solutions
Table S3 shows the model fit indices of a one- to six-class model of SES among those who met criteria for a mental health problem. A four and five-class model indicated good fit based on these having lower AIC, BIC and SSABIC values, while also having a high entropy value. The biggest drop in AIC BIC and SSABIC values were observed from a three to four-class model and further inspection of the classes between the four and five-class models suggested that the additional class was mainly defined by lower supervisory occupations and thus less parsimonious.
Descriptions of four-class model
Table S4 shows the probability of being assigned to each of the four classes based on individual SES indicators. An overview of each class is provided below. A sensitivity analysis showed that 36.03% of those with a CMD were “routine/intermediate occupation, GCSE-level educated, mixed owner/renters” whereas 18.94% were “retired, no formal educated, homeowners”. Of those with a SMI, 42.87% were “economically inactive, GCSE-level and lower educated, social renters” whereas 8.56% were “retired, no formal educated, homeowners” (Table S4).
Class one—“Economically inactive, GCSE-level and lower educated, social renters” (N = 341, 19.25%), probability of correct identification = 88.0%)
There were approximately an equal number of males and females in this class, with half aged 35–54, of White ethnicity, and half single (Table 1). The majority of this group (80.00%) were not working/have not worked in the past year, 42.00% in debt and 84.00% in receipt of any out of work benefits. While 46.00% were educated to A-Level or GCSE level and 43.00% had no educational qualifications. Regarding housing tenure, 64.00% of this group were social renters and more likely to live in a household with another adult, without children, compared to living alone, without children (Table S4).
Class two—“Routine/intermediate occupation, GCSE-level educated, mixed owner/renters” (N = 440, 42.24%), probability of correct identification = 93.30%)
There were an equal number of males and females in this class, two thirds were aged 16–34, the majority of White ethnicity, and two thirds single (Table 1). The majority of this group were in routine or intermediate occupations (66.00%) with 84.00% not in debt and 96.00% not in receipt of any out of work benefits. While 72.00% were educated to A-Level or GCSE level, 46.00% were homeowners and, also more likely to live in a household on their own, without children (Table S4).
Class three—“Retired, no formal education, homeowners” (N = 311, 16.31%), probability of correct identification = 87.60%)
Nearly two-thirds of this group were female, all aged 55 or over, of White ethnicity, and half married or in a civil partnership (Table 1). Most were retired (76.00%) and homeowners (72.00%). The majority were not in debt (95.00%) and 95.00% were not in receipt of any out of work benefits. Within this group, 44.00% had no qualifications and more likely to live in a family household, compared to living on their own, without children (Table S4).
Class four—Professional occupation, degree-level educated, homeowners” (N = 339, 22.20%), probability of correct identification = 92.00%)
There were an equal proportion of males and females in this class, half aged 35–54, the majority of White ethnicity and half married or in a civil partnership (Table 1). Most were in managerial or professional occupations (76.00%), 95.00% were not in debt and 99.00% were not in receipt of any out of work benefits. Sixty-seven percent were educated to degree level while 70.00% were homeowners. This group were more likely to live in a family household, compared to living alone, without children (Table S4).
Associations of SES with alcohol use
Table 2 shows the frequency and associations of the SES classes with non-drinking, hazardous and harmful/probable dependence. The highest prevalence of non-drinking was among “economically inactive, GCSE-level or lower educated, social renters” and “retired, no formal education, homeowners” (35.94% and 34.99%, respectively) whereas the lowest prevalence was among “professional occupation, degree-level educated, homeowners” (10.23%). Over 25% of “routine/intermediate occupation, GCSE-level educated, mixed owner/renters” and “professional occupation, degree-level educated homeowners” reported hazardous use compared to 14.65% of “economically inactive, GCSE-level or lower educated, social renters” and 9.09% “retired, no formal education, homeowners”. Whereas 10.99% of “economically inactive, GCSE-level or lower educated, social renters” reported harmful/probable dependence compared to 3.87% of “retired, no formal education, homeowners” but proportions were similar between “routine/intermediate occupation, GCSE-level educated, mixed owner/renters” and “professional occupation, degree-level educated homeowners”.
Compared to “professional occupation, degree-level educated, homeowners”, all other SES classes had increased odds of non-drinking with associations strongest among “economically inactive, GCSE-level or lower educated, social renters” (OR = 4.96, 95%CI 3.10–7.93, see Table 2), only “retired, no formal education, homeowners” had decreased odds of hazardous use (OR 0.35, 95%CI 0.20–0.59, see Table 2). No associations between SES classes and harmful/probable dependence were found (see Table 2).
Indirect effect of associations between SES and alcohol use via social support and neighbourhood environment
Social support
The mean social support score was 19.25 (SD = 3.02), indicating moderate levels of social support. Compared to “Professional occupation, degree-level educated, homeowners”, all other SES classes reported significantly lower social support scores (see Fig. 2). A higher social support score (compared to lower) was associated with a decreased odds of non-drinking and harmful/probable dependence, respectively (see Fig. 2). Associations between SES and non-drinking via social support were significant among “economically inactive, GCSE-level or lower educated, social renters” and “retired, no formal education, homeowners” (see Table 3), indicating that lower social support facilitated non-drinking among these groups. Whereas associations between “economically inactive, GCSE-level or lower educated, social renters” and harmful/probable dependence via social support was significant which suggests that lower social support also facilitated lower odds of harmful/probable dependence among this group.
Neighbourhood environment
The mean neighbourhood environment score was 20.63 (SD = 7.42), indicating moderate levels of disadvantage. Compared to “professional occupations, degree-level educated, homeowners”, “economically inactive, GCSE-level or lower educated, social renters” reported higher neighbourhood environment scores whereas “retired, no formal education, homeowners” reported lower scores (see Fig. 2). An increase in neighbourhood environment was associated with increased odds of harmful/probable dependence, compared to low-risk drinking (see Fig. 2). Associations between “economically inactive, GCSE-level or lower educated, social renters” and harmful/probable dependence via neighbourhood environment was significant (see Table 3), indicating that among lower SES groups with a mental health problem, living in a worse neighbourhood environment played a role in the likelihood of harmful drinking.
Discussion
Key findings
This study aimed to examine SES classes of individuals who met criteria for a mental health problem, how SES was associated with alcohol use within this sample and examine the indirect effects via social support and neighbourhood environment. Four classes of SES were identified; “economically inactive, GCSE-level or lower educated, social renters”, “routine/intermediate occupation, GCSE-level educated, mixed owner/renters”, “retired, no formal education, homeowners”, and “professional occupation, degree-level educated, homeowners”, which occupation, GCSE-level educated, mixed owner/renters”. Compared to “professional occupation, degree-level educated, homeowners”, all other SES classes reported moderate to strong associations with non-drinking, while “retired, no formal education, homeowners” also reported decreased odds of hazardous use. The study found some evidence of an indirect effect of social support and neighbourhood environment with associations between “economically inactive, GCSE-level or lower educated, social renters” and non-drinking, and harmful/probable dependence, respectively.
Links with previous research
SES classes among individuals who met criteria for a mental health problem reported in this study indicates that those with a mental health problem presented from a range of SES backgrounds which is in contrast to the social causation hypothesis where individuals report poor mental health because of their SES [10]. Our findings may be explained by the broad scope of mental health problems as we found that the prevalence of “economically inactive, GCSE-level educated, social renters” was highest among those who met criteria for a SMI and this is consistent with some previous research on lower individual and parental SES and more severe mental health problems [53, 54].
We hypothesised that more advantaged SES classes would have increased odds of non-drinking and decreased odds of harmful drinking, however, compared to “professional occupation, degree-level educated, homeowners”, we found that all other lower SES classes were more likely to report non-drinking. These findings may be explained by the “sick-quitter” hypothesis which suggests that individuals no longer drink because they were a previous harmful drinker [55] or have a pre-existing condition [56], which in the context of this study was having a mental health problem. However, it was not possible to explore the reasons for non-drinking in this sample.
We hypothesised that more disadvantaged SES classes would have increased odds of harmful/probable dependence, however, no associations were found, compared to “professional occupation, degree-level educated, homeowners” among individuals who met criteria for a mental health problem. The alcohol harm paradox argues that those of lower SES are more likely to experience alcohol harms despite drinking at lower levels [9] which has been consistently supported by previous research conducted in the general population [12, 14]. A recent study, which used LCA to derive SES, found higher levels of harmful drinking in “economically inactive homeowners” and “professional renters” compared to “professional homeowners” respectively in the general population [19]. While this contradicts our current findings, both showed that occupational grade and housing tenure were associated with alcohol use but there may be differences in how these were associated due to our sample being restricted to those who met criteria for a mental health problem, and the potential for the lack of associations with harmful/probable dependence being explained by participants being former harmful drinkers. While both the current study and Boniface and colleagues study [19] are limited by the cross-sectional design of the data, a review of the associations between SES and alcohol use has indicated that housing status is a predictor of alcohol use and negative alcohol-related consequences within the general population [57]. The longitudinal association between SES, alcohol use and social support has been seldom explored among individuals with a mental health problem. Our findings highlight the need for further research examining the longitudinal associations between SES and alcohol use (including non-drinking) among those with a mental health problem, particularly among the most deprived groups.
Some of the associations between SES and alcohol use were partially explained by lower social support and living in a worse neighbourhood environment, specifically the increased odds of non-drinking in the “economically inactive, GCSE-level or lower educated, social renters”, and harmful/probable dependence, and “retired, no formal education, homeowners” and non-drinking respectively. It can be argued that those from lower SES backgrounds have more barriers and less opportunities to create social support [21, 22] or that social support acts as a buffer against the use of alcohol when under stress [23]. Findings from this study suggest that decreased social support increased the odds of non-drinking and harmful/probable dependence, respectively. It may be the type of social support an individual has which might explain the significant findings to two different drinking patterns [24, 25].
In addition, when neighbourhood environment was considered, associations between SES and harmful/probable dependence was partially explained by living in a worse neighbourhood environment, specifically in partially explaining the increased odds of harmful/probable dependence in the “economically inactive, GCSE-level or lower educated, social renters”. While some of our findings contrast the social causation hypothesis [10], the indirect effect of neighbourhood environment indicate that the most deprived SES groups living in the most deprived areas may use alcohol to cope. Previous research has also shown an increase in alcohol consumption among men living in disadvantaged neighbourhoods [58], and an increase in severe hazardous drinking among women living in disordered neighbourhoods [59].
Strengths and limitations
The current study is one of the first to show differences in associations among individuals who met criteria for a mental health problem which contrasts with findings from general population samples. We used a range of measures to capture different aspects of SES to develop a more holistic understanding of SES among this population. We also showed that social contexts, such as social support and neighbourhood environment, play a role in the associations between SES and alcohol use, which can be used to provide more tailored interventions towards the most deprived SES groups.
However, while individuals who met criteria for a mental health problem presented from a range of SES backgrounds, there may have been differences in these classes based upon the severity of the mental health problem as indicated by our sensitivity analysis, but we did not have enough statistical power to examine this in our multinomial regression and structural equation models. Further, the data used in this study was collected in 2014–2015, however, this data is the most comprehensive dataset of mental health problems in the UK general populations, therefore, was the most suitable dataset to use considering the aims of the study. Lastly, due to the cross-sectional nature of the data, it is not possible to conclude the directionality of the association between SES and alcohol use, including the indirect effect of social support and neighbourhood environment. Nonetheless, the current study provides some insight into the potential importance of decreased social support and living in a deprived neighbourhood environment, particularly among those from the lowest SES background who have a mental health problem using a nationally representative dataset.
Conclusions
Individuals who met criteria for a mental health problem presented from a range of SES backgrounds. Compared to “professional occupation, degree-level educated, homeowners”, those of lower SES had increased odds of non-drinking. No associations between SES and harmful/probable dependence were found which contrasts with the alcohol harm paradox, however, when social support and neighbourhood environment were assessed, there were some associations among the most deprived SES group. Future research should examine the mechanisms of non-drinking and the role of social support and neighbourhood environment among individuals with a mental health problem.
