Inconsistent health perceptions for US women and men with diabetes

Background: Two health status measures for adults with diabetes are compared in order to identify gender-based differences between norm-based scores for health status and self-rated health scores. Methods: Data were obtained from the 2001 and 2003 Medical Expenditure Panel Survey(MEPS). Diabetes was identified by self-report or ICD-9 code. Demographic and clinical (e.g., body mass index [BMI], comorbidities) parameters were included. Outcomes were norm-based measures of physical and mental health (SF-12 Physical and Mental Component Scores: SF-12 PCS and SF-12 MCS) and self-rated perception of health status. Sex-based differences in the three outcome measures, SF-12 PCS, SF-12 MCS, and self-rated health scores, were evaluated in univariate analyses and multivariate linear regression for survey data. Results: A cohort of 3640 respondents with diabetes was identified (2037 women, 1603 men). In unadjusted analyses, women were older than men (60.7 vs. 59.3 years, p < 0.001), reported higher mean BMI (31.1 vs. 30.4), more comorbidities, depression, and physical limitations (all p < 0.001), had poorer SF-12 MCS scores (p = 0.01), and self-rated their health status significantly higher than did men (p < 0.01). In adjusted analyses, female gender was associated with lower SF-12 MCS scores and higher self-rated health scores. No factors were positively associated with higher scores across all three measures; only cognitive limitations consistently predicted lower health status scores in all three measures. Conclusions: Among adults with diabetes in a nationally representative sample of the U.S. adult population, discrepancies exist in health status measures. Despite being older, having more comorbidities and physical limitations, and lower norm-based scores for mental functional status, women self-rate their own health status higher than do men. Further research into the gender-based determinants and clinical implications of self-rated health status is warranted.
