Associations of physical function and health-related quality of life in 297 rural women, ages 40–69 years (body mass index of 28–45 kg/m2) who met activity criterion were examined using cross-sectional baseline data from the Women Weigh-in for Wellness trial (ClinicalTrials.gov NCT01307644). Assessments included demographics, 400-m walk, timed chair stands, and health-related quality of life using the Patient-Reported Outcomes Measurement Information System (PROMIS-29). Women were classified as active if they had ≥500 metabolic equivalent·min/week by the Behavioral Risk Factor Surveillance System survey (n = 103, 34.7%), or ≥150 weekly minutes of greater than or equal to moderate intensity activity by accelerometry (n = 222, 74.8%). Ordinal logistic regression models adjusted for age, comorbidities, and body mass index were calculated. Meeting activity guidelines per self-report was associated with perceptions of less fatigue and greater satisfaction with social roles, whereas meeting guidelines as measured by accelerometry was associated with faster gait speed.

This study investigated physical activity and fitness of midlife and older rural women. Random-digit dialing was used to recruit 225 women (57.9 ± 5.6 years old). Self-reported activity (moderate activity, flexibility, and strength) and fitness (body composition, flexibility, strength, and estimated VO2max) were assessed. The women demonstrated low daily energy expenditure (30.74 ± 10.63 kcal · kg−1 · day−1) and estimated VO2max (20.12 ± 7.81 ml · kg−1 · min−1), with 51.5% reporting fair or poor health. Few women reported meeting Healthy People 2010 targets for moderate activity (43.1%), flexibility (28.9%), or strength (14.2%). When classified by estimated VO2max into three categories, differences were observed for body-mass index, percent body fat, sit and reach, and timed chair stands, with the poorest performance by those with low cardiorespiratory fitness. Adherence to Healthy People 2010 targets for moderate activity and strengthening was associated with higher cardiorespiratory fitness. These rural women are targets for physical activity interventions because of their sedentary behaviors and low cardiorespiratory fitness.
