Background:

The current study evaluated the feasibility and effectiveness of a diet and physical activity intervention for homeless adults.

Methods:

Shelter residents (N = 32) were randomly assigned to a 4-week diet and physical activity intervention (n = 17) or an assessment-only control group (n = 15). Intervention participants received tailored educational newsletters, pedometers with step goals, and twice daily fruit/vegetable snacks. Key measures included 24-hour dietary recall interviews and accelerometer-measured moderate-to-vigorous intensity physical activity (MVPA).

Results:

At baseline, 68.8% of participants were overweight or obese, 93.8% reported food insecurity, and 43.8% reported activity levels below physical activity guidelines. Baseline dietary recall interviews indicated low fruit/vegetable consumption, and elevated intake of added sugar, saturated fat, and sodium relative to current dietary recommendations. During the 4-week study period, intervention participants engaged in significantly greater accelerometer-measured daily MVPA (P < .001) than controls (median = 60 daily minutes p vs. 41 daily minutes). Between groups differences in fruit/vegetable consumption at the end of treatment did not reach statistical significance. Most participants reported that the intervention was helpful for increasing fruit/vegetable intake and physical activity.

Conclusions:

Findings highlight the potential to improve dietary quality and increase physical activity among sheltered homeless adults.

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.
