Research suggests that overweight and obesity are associated with depressive symptoms, particularly among women. Evidence from weight control trials suggests that higher weighing frequency is associated with greater weight loss or less weight gain. As limited data exist on the effects of self-weighing on body mass index (BMI) among overweight adults with or without depression, this study seeks to examine this issue using data from a population-based epidemiologic survey.
Data from a large population-based survey of 4655 women ages 40-65 in the greater Seattle area, surveyed from November 2003 to February 2005, were used to examine associations of depression and weight self-monitoring with BMI. Sample-weighted regression models were used to examine associations of depression, self-weighing frequency, and BMI, with demographic factors (race/ethnicity, employment status, smoking status, age, martial status, educational attainment) entered as covariates.
Regression models indicated that higher self-weighing frequency and negative depression status were independently associated with lower BMI, with no interaction observed between depression and self-weighing.
Frequent self-weighing appears to be associated with lower BMI in both depressed and non-depressed overweight women.

    • "Changes in weight are the main indicator used to gauge dieting success and, accordingly, most organized diet centers require weekly weigh-ins. Frequent weighing is associated with successful weight loss and weight maintenance among adult samples (Butryn, Phelan, Hill, & Wing, 2007; Jeffery & French, 1999; Linde et al., 2007; Linde, Jeffery, French, Pronk, & Boyle, 2005; Wing et al., 2007).

    ABSTRACT: This study investigated weighing and body-monitoring behaviors, as well as psychological and behavioral reactions to weighing, among female college students. Weighing and body monitoring were engaged in by the majority of participants. Participants changed food intake and exercise based on weight. About 63% reported that the scale number impacts their mood, and 50% and 48% indicated that it impacts their sexual comfort and self-esteem, respectively. Most did not perceive self-weighing to be harmful. College counselors should be aware that weighing and body monitoring are normative, with negative psychological outcomes associated with weighing for a substantive percentage of college women.

    • "However, this study found that there was no significant relationship between exercise self-efficacy, and BMI and WC. Exercise self-efficacy may be associated with physical activity practices rather than directly influencing BMI and WC, as Linde et al. (2007) found that selfefficacy may influence weight control behaviors resulting in effective weight control behaviors that affect weight change [19]. Although the literature shows that the number of barriers to exercise increased with age and BMI category in the general population [28] [29], there are no consistent associations between perceived barriers and BMI and WC reported for working adults.

    ABSTRACT: Socio-economic status, lifestyle behaviors, and psychosocial factors have been implicated in the development of overweight and obesity. This study aims to observe the prevalence of overweight and obesity in an academic worksite and to examine the possible association between variables such as socio-economic characteristics, work factors, psychosocial factors, and weight control behaviors and obesity. In this study, the target population were full-time academic and non-academic staff. Body mass index (BMI) and waist circumference (WC) were computed to determine obesity. A pretested self-administered questionnaire was used to obtain information on socio-demographic factors, work related factors, psychosocial factors, and weight control behaviors. Data were obtained on 367 adults of whom 39.2% were males and 60.8% females. Overweight was seen in 31.9% of males and 26.5% of females while 16.1% of them were obese, irrespective of gender. Central obesity was noted in about 37% of males and 39% of females. The results showed that socio-demographic factors (age, gender, and education) and psychosocial factors (perceived health status, body weight perception, and weight-control goals) were significantly associated with BMI. Working hours were also significantly associated with BMI. However, weight control practices (diet-control practices and physical activity practices) were not significantly associated with BMI. In conclusion, this study found a higher prevalence of overweight and obesity among employees of a selected public university in comparison to the general population. Socio-demographic, psychosocial factors, and working hours were found to contribute to obesity in this sample of adults.

    • "The long follow-up and large sample sizes were strengths in both samples, but attrition bias was especially concerning in the Weight to Be sample. Linde, et al. (2007) 27 4,660 female participants recruited from a health plan in Washington. The mean age was 52 years and the mean BMI was 28 kg/m 2 . "

    ABSTRACT: Regular self-weighing has been a focus of attention recently in the obesity literature. It has received conflicting endorsement in that some researchers and practitioners recommend it as a key behavioral strategy for weight management, while others caution against its use due to its potential to cause negative psychological consequences associated with weight management failure. The evidence on frequent self-weighing, however, has not yet been synthesized. The purpose of this paper is to evaluate the evidence regarding the use of regular self-weighing for both weight loss and weight maintenance. A systematic literature review was conducted using the MEDLINE, CINAHL, and PsycINFO online databases. Reviewed studies were broken down by sample characteristics, predictors/conditions, dependent measures, findings, and evidence grade. Twelve studies met the inclusion/exclusion criteria, but nearly half received low evidence grades in terms of methodological quality. Findings from 11 of the 12 reviewed studies indicated that more frequent self-weighing was associated with greater weight loss or weight gain prevention. Specifically, individuals who reported self-weighing weekly or daily, typically over a period of several months, held a 1 to 3 kg/m2 (current) advantage over individuals who did not self-weigh frequently. The effects of self-weighing in experimental studies, especially those where self-weighing behaviors could be isolated, were less clear. Based on the consistency of the evidence reviewed, frequent self-weighing, at the very least, seems to be a good predictor of moderate weight loss, less weight regain, or the avoidance of initial weight gain in adults. More targeted research is needed in this area to determine the causal role of frequent self-weighing in weight loss/weight gain prevention programs. Other open questions to be pursued include the optimal dose of self-weighing, as well as the risks posed for negative psychological consequences.
