Weight and social comparison: Does the weight of a stranger affect a person's perception of their own weight?

Research suggests that social context affects individuals' perception of their own weight. Using face-to-face interviews as the social context, we analyze the effect of interviewers' (N = 90) body mass index on respondents' (N = 3068) self-perceived weight level. Respondents reported a higher weight level when the interviewer had a higher body mass index (absolute social comparison). Female respondents reported a lower weight level if interviewers had a higher body mass index than they did (relative social comparison). Results suggest that weight perception reflects both absolute and relative social comparison, especially among women. Future research should consider causation and self-selection when studying social context and body image.

Hearing loss and disability exit: Measurement issues and coping strategies.

Hearing loss is one of the most common conditions related to aging, and previous descriptive evidence links it to early exit from the labor market. These studies are usually based on self-reported hearing difficulties, which are potentially endogenous to labor supply. We use unique representative data collected in the spring of 2005 through in-home interviews. The data contains self-reported functional and clinically-measured hearing ability for a representative sample of the Danish population aged 50-64. We estimate the causal effect of hearing loss on early retirement via disability benefits, taking into account the endogeneity of functional hearing. Our identification strategy involves the simultaneous estimation of labor supply, functional hearing, and coping strategies (i.e. accessing assistive devices at work or informing one's employer about the problem). We use hearing aids as an instrument for functional hearing. Our main empirical findings are that endogeneity bias is more severe for men than women and that functional hearing problems significantly increase the likelihood of receiving disability benefits for both men and women. However, relative to the baseline the effect is larger for men (47% vs. 20%, respectively). Availability of assistive devices in the workplace decreases the likelihood of receiving disability benefits, whereas informing an employer about hearing problems increases this likelihood.

Gendered perceptions of own and partner weight-level.

This study investigates gender differences in perceptions of body weight. Previous research has found significant gender differences in perceived weight-level, but less is known about weight perceptions of the opposite gender. Based on Danish survey data (859 women and 160 men), the discrepancy between BMI weight-level and self-perceived weight-level is estimated as well as the perception of one's partner's weight-level. Two main empirical conclusions emerge. First, there are significant gender differences in weight assessment. Whereas women assess weight according to the standardized BMI weight-levels for both genders, men assess weight according to gender. The weight-level of men is often underestimated by men themselves, but both men and women tend to overestimate the weight-level of women in the lower BMI deciles compared to standardized BMI weight-levels. Second, there is greater underestimation of weight-levels for individuals in the higher BMI--especially regarding weight perceptions of the opposite gender. These findings are discussed within a framework of socio-cultural theory of body image and gendered relations.

The effect of home care on the ability to perform the activities of daily living and the well-being of older people.

With the considerable changes in population age-profiles, the preventive care of older people is becoming more and more important. We analyse the long-term effect of the provision of home care on the recipient's ability to perform the activities of daily living (ADLs) and upon aspects of their well-being. Using regression analysis on a set of Danish longitudinal data featuring people aged 67-77 we estimate the effect of home care while controlling for initial health, including initial ADL ability and well-being, along with demographic and socioeconomic conditions. We find no effect of home care on ADL ability in women; results for men, however, indicate a negative association. The provision of home care has an insignificant effect on women's well-being, but a positive effect for men incapacitated beyond a certain degree. Results indicate a need for supplementary efforts to protect against the disablement process.
