Background:

This study was done to determine whether physical activity at baseline is independently associated with musculoskeletal pain and fulfilling one’s physical role over 3 subsequent years.

Methods:

Our research involved a 3-year longitudinal study of over 2400 community-dwelling, midlife women from the Study of Women’s Health Across the Nation (SWAN). Measurements included baseline physical activity using the Kaiser Permanente Health Plan Activity Survey and SF-36 role-physical and bodily pain indices at each of 3 annual follow-up visits.

Results:

Each 1-point increase on the physical activity score was associated with a 7% greater likelihood of a high role-physical score (95% CI = 1.02– 1.13) and a 10% greater likelihood of a low bodily pain score (95% CI = 1.04–1.17) after adjusting for age, race, menopausal status, educational level, body mass index, depressive symptoms, smoking, and chronic medical conditions. The association between physical activity level and role-physical score was eliminated in the fully adjusted model after adjustment for pain level in post hoc analysis [OR = 1.04 (95% CI = 0.98–1.09)].

Conclusion:

This study demonstrates that women who are more physically active at midlife experience less bodily pain over time regardless of menopausal status, sociodemographics, and medical conditions. Higher physical activity level positively impacts fulfilling one’s physical role; however, this is mediated by pain level.

Background:

Physical inactivity in midlife women is associated with increased intra-abdominal adipose tissue development. We describe an innovative multimethod study 1) to better understand barriers to physical activity (PA) and 2) to engage midlife women to product test physical activities and identify local community-based providers and sustainable and fun PA experiences.

Methods:

Formative research on PA barriers from the Chicago site Study of Women’s Health Across the Nation (SWAN) ancillary study of midlife women was used to develop a pilot testing measure. Feasibility, acceptability and sustainability of the PA activities were determined using the measure.

Results:

Desirable locations and/or instructors were identified. The first 2 groups identified, pilot tested, and then ranked activities for their ability to promote sustained PA. The 6 top-ranked were: circuit training, total body fitness, kickboxing, Zumba, Pilates, and pedometer. The final group pilot tested highly ranked PA in 2-week blocks, and ranked pedometer and Zumba in their top 3.

Conclusion:

Consensus was reached regarding activities that could be valuable in promoting sustained PA in midlife women. Choosing convenient sites and popular instructors further facilitates sustainability. Building relationships with key community partners is essential for sustainability. Community-based participant involvement in study design is a critical element in developing a healthy living intervention.

Purpose: To examine racial/ethnic differences in participant-reported and device-based estimates of sedentary and physical activity behaviors and correlations between measurement methods in midlife and young-old women. Methods: Data are from 1,257 Study of Women’s Health Across the Nation participants, aged 60–72 who agreed to participate in an accelerometer protocol and had valid wear time (46% White, 26% Black, 12% Chinese, 10% Japanese, 6% Hispanic). Measures from the Kaiser Physical Activity Scale (KPAS) and ActiGraph wGT3X-BT were summarized overall and by race/ethnic groups. Partial Spearman rank order correlation coefficients between the KPAS and accelerometer were computed overall and by race/ethnic groups. Fisher’s z transformation-derived confidence intervals were calculated to evaluate differences in observed correlations in the various race/ethnic groups, compared to White women. Results: Participants spent an average of 7.5 ± 2.1 h·d−1 in sedentary behaviors, 4.5 ± 1.1 h·d−1 and 2.3 ± 0.8 h·d−1 in low or high light intensity physical activity, respectively, and 56 ± 35 min·d−1 in moderate-to-vigorous intensity physical activity. Time spent in each category differed by race/ethnic group. Overall, correlation coefficients comparing the KPAS domain-specific and total physical activity scores with accelerometry were low to moderate (range: 0.062–0.462), and few statistically significant differences in correlations were noted for race/ethnic groups, compared to White women. Conclusions: Study findings complement prior studies describing sedentary and physical activity behaviors using multi-methods in a diverse population of older women, and provide additional evidence on the convergent validity of the KPAS by race/ethnic groups.
