Background

Studies have shown that frequent self-weighing is a valuable tool for weight loss and weight loss maintenance. However, self-weighing practices among adults, independent of a weight loss program, are largely unknown. Purpose: To investigate the frequency of self-weighing among adults and whether self-weighing frequency (SWF) was associated with markers of health.

Methods

533 U.S. adults completed a questionnaire on SWF and other health markers. Respondents were categorized into 4 quartiles of SWF: “Never,” “<1x a week,” “1x a week,” or “>1x a week.”

Results

24.2% of adults never weighed, 35.1% weighed <1x week, 23.8% weighed 1x a week, and 16.9% weighed >1x a week. There was no difference in the sex or BMI distribution across SWF quartiles (p>0.5). More frequent self-weighing was significantly associated with higher income, less sedentary time, more vigorous physical activity (PA) and several healthier practices including reading nutrition labels, eating whole grains, having knowledge of the Dietary Guidelines for Americans, drinking less soda, self-monitoring food, PA and weight change, and choosing lower-calorie options (p<0.05 for all). Conversely, there were no significant differences in body mass index (BMI), age, stress, education, employment status sleep time, smoking or alcohol consumption, screen time, or chronic diseases between the SWF quartiles.

Conclusions

While SWF was associated with some markers of health including vigorous PA levels, less sedentary time, and several healthier dietary habits, it was not linked to BMI, stress, screen time, or chronic diseases.
