RESUMEN
Successful community-level health initiatives require implementing an effective portfolio of strategies and understanding their impact on population health. These factors are complicated by the heterogeneity of overlapping multicomponent strategies and availability of population-level data that align with the initiatives. To address these complexities, the population dose methodology was developed for planning and evaluating multicomponent community initiatives. Building on the population dose methodology previously developed, this paper operationalizes dose estimates of one initiative targeting youth physical activity as part of the Kaiser Permanente Community Health Initiative, a multicomponent community-level obesity prevention initiative. The technical details needed to operationalize the population dose method are explained, and the use of population dose as an interim proxy for population-level survey data is introduced. The alignment of the estimated impact from strategy-level data analysis using the dose methodology and the data from the population-level survey suggest that dose is useful for conducting real-time evaluation of multiple heterogeneous strategies, and as a viable proxy for existing population-level surveys when robust strategy-level evaluation data are collected.

The effects of experimentally induced and personally relevant stressors on low back EMG activity during 3 phases of the menstrual cycle in women with the premenstrual syndrome (PMS) and premenstrual low back pain were examined. Thirty-nine women reporting either PMS and premenstrual severe low back pain (group 1), PMS with premenstrual moderate low back pain (group 2), or those reporting neither condition (group 3) participated. During each of 3 menstrual phase-specific assessment sessions, participants were exposed to a neutral stimulus, an experimentally induced stressor, and 2 personally relevant stressors in a randomized order. Concomitant monitoring of low back EMG activity and heart interbeat interval was undertaken. Results indicated that participants in group 1 evidenced greater EMG changes in response to personal stressors compared to the neutral stimulus and experimentally induced stress during the premenstrual phase. EMG activity in response to personal stress was also significantly higher during the premenstrual phase than during the menstrual and intermenstrual phases for group 1, and higher than EMG changes evidenced by groups 2 and 3 during the same phase. Group 2, while not reporting as severe premenstrual back pain as did group 1, reported moderate levels of back pain and evidenced greater physiological reactivity to a personal stressor than did group 3. The findings highlight the link between personally relevant stressors and concomitant physiologic responsivity and the role that this arousal may play in the maintenance and exacerbation of premenstrual low back pain.
