Self-monitoring of body weight is associated with lower body mass index (BMI) and greater weight loss. Although regular self-weighing is also related to lower BMI in overweight patients with type 2 diabetes, the relationship between self-weighing and glycemic control has not been fully investigated. This study examined the cross-sectional association between self-weighing and glycated hemoglobin (HbA1c) of 306 outpatients with type 2 diabetes. There were 192 men and 114 women (mean age 62.3 ± 12.2 years). HbA1c was significantly lower in patients who weigh themselves more than once a day than in those who do not have a habit of daily self-weighing (7.10 ± 1.08 vs. 7.66 ± 1.30 %; P < 0.0005), even though there are no significant differences in body mass index (BMI) between groups. Higher weighing frequency and weighing in the morning was also associated with lower HbA1c. These findings raise the possibility that frequent self-weighing contributes to favorable glycemic control independent of prospective weight loss. The study suggests that daily self-weighing should be recommended for type 2 diabetes patients as a clinical health message about glycemic control. Further studies in a larger number of patients are needed to explore the effects of weighing frequency in these contexts.
