Gender differences in seeking care for falls in the aged Medicare population.

Background: One third of adults aged ≥65 years fall annually, and women are more likely than men to be treated for fall injuries in hospitals and emergency departments.

Purpose: The aim of this study was to examine how men and women differed in seeking medical care for falls and in the information about falls they received from healthcare providers.

Methods: This study, undertaken in 2010, analyzed population-based data from the 2005 Medicare Current Beneficiary Survey (MBCS), the most recent data available in 2010 from this survey.

Sex differences in child nutritional and immunological status 5-9 years post contact in fringe highland Papua New Guinea.

Objectives: This study examines sex differences in vulnerability among children experiencing rapid culture change that may reflect distinct microecologies driven by differential parental investment and/or sex-specific life history strategies. Apparent female growth canalization may be a life history strategy favoring growth over maintenance but also may reflect sex-differentiated selection for resilience based on unequal treatment during early life.

Methods: Stature, weight, and serum measures of C-reactive protein (CRP, an inflammation marker) and Epstein-Barr Virus antibodies (EBV, a humoral immune response marker) were collected longitudinally among children/adolescents ages 5-20 years (N = 65), 5-9 years after sustained contact in a fringe highland hunter-horticulturalist group from the Schrader Range in Papua New Guinea exhibiting male preference and sex-biased survival.
