Evaluation of Light Physical Activity Measured by Accelerometry and Mobility Disability During a 6-Year Follow-up in Older Women.

Importance: Almost 1 in 4 women older than 65 years is unable to walk 2 to 3 blocks, and mobility disability is a key factor associated with loss of independence. Lack of moderate to vigorous-intensity physical activity is associated with mobility disability, but whether lighter physical activity is associated with mobility disability is unknown.

Objective: To determine the association of light-intensity physical activity and incident mobility disability among older women.

The Relationship of Accelerometer-Assessed Standing Time With and Without Ambulation and Mortality: The WHI OPACH Study.

Background: Self-reported time spent standing has been associated with lower risk of mortality. No previous studies have examined this association using device-measured standing.

Method: This was a prospective cohort study of 5878 older (median age = 80 years), racial/ethnically diverse, community-dwelling women in the WHI Objective Physical Activity and Cardiovascular Health Study (OPACH).

Alcohol use and its association with sexual risk behaviors in the Armed Forces of the Republic of the Congo.

Background: Previous research has shown alcohol misuse amplifies the risk of acquiring sexually transmitted infections [STIs], including HIV, by increasing high risk sexual behaviors. Military populations are particularly vulnerable to both alcohol misuse and STIs due to the unique conditions of military service. This study estimated the prevalence of probable hazardous and harmful alcohol use and examined associations with transactional sex, sex with a sex worker, and multiple sexual partners among military personnel in the Armed Forces of the Republic of the Congo (FAC).
