简要总结
Despite the health benefits of physical activity, increasing regular physical activity levels among low-income, ethnic-minority mothers has remained a significant challenge. The current mixed-methods feasibility study explored the impact that a three-month community-based (CBI) and a home-based intervention (HBI) had on improving physical activity and fitness levels, as well as psychosocial outcomes (self-efficacy and social support) among low-income, ethnic-minority mothers. These results support the efficacy of CBIs and HBIs in improving PA and fitness levels and have important implications for improving health outcomes among low-income, ethnic-minority mothers.
详细描述
Despite the health benefits of physical activity, increasing regular physical activity levels among low-income, ethnic-minority mothers has remained a significant challenge. Yet, few studies have examined the feasibility of implementing interventions to address physical activity barriers often experienced by this population. The current mixed-methods feasibility study explored the impact that a three-month community-based (CBI) and a home-based intervention (HBI) had on improving physical activity and fitness levels, as well as psychosocial outcomes (self-efficacy and social support) among low-income, ethnic-minority mothers. Thirty mothers were randomized to either a three-month community-based intervention (CBI) or a home-based intervention (HBI) and completed pre- and post-intervention assessments of physical activity (self-report, accelerometer), fitness (cardiorespiratory, muscle endurance and strength, flexibility), self-efficacy, and social support. Post-intervention focus groups were also conducted. Through formative research, this pilot work will develop and empirically test a CBI and HBI among low-income mothers for use in local community centers. The results of the proposed work have substantial public health implications and are expected to advance the investigator's understanding of how low-income mothers effectively use these intervention modalities to adopt healthy behaviors and produce change that can positively impact their health, as well as that of their children. Further, the proposed research will yield two physical activity interventions that can be readily delivered in community settings, are scalable, and are relatively low cost. Finally, these results will help identify those subgroups of mothers that may do particularly well (or poorly) with these innovative approaches to physical activity adoption and maintenance. This has important implications for the tailoring of physical activity programs to individual needs and preferences.

结局指标
主要结局
Change in Muscle Endurance from baseline to 3 months post-intervention
时间窗: Muscle endurance assessments were conducted at baseline and at one, two, and three months post-intervention.
Muscle endurance was assessed by the number of modified push-ups completed in correct form, with a greater number of 90° push-ups completed representing greater muscular endurance.
Change in Cardiorespiratory Fitness from baseline to 3 months post-intervention
时间窗: Cardiorespiratory fitness assessments were conducted at baseline and at one, two, and three months post-intervention.
Cardiorespiratory fitness was assessed via predicted relative maximum oxygen consumption, also known as relative VO2 max (ml/kg/min) after participants completed a timed mile walk, with a greater relative VO2 max being an indicator of greater cardiorespiratory fitness.
Change in Physical Activity from baseline to 3 months post-intervention
时间窗: Self-reported and fitbit physical activity assessments were conducted at baseline and at one, two, and three months post-intervention.
Self-reported duration of moderate/vigorous physical activity was assessed using the Check and Line Questionnaire (CALQ), with higher numbers representing greater average minutes of moderate/vigorous-intensity PA completed/day over a three-day assessment period. Objective physical activity was assessed using the Fitbit One (2009 version), which is an accelerometer worn on the hip (clipped to a participant's clothing at the waist). For the current study, very active minutes were examined (measure of basal metabolic rate/minute). Activity data was averaged across the three days that the Fitbit was worn, with greater number of very active minutes indicating greater daily moderate/vigorous-intensity physical activity levels.
Change in Flexibility from baseline to 3 months post-intervention
时间窗: Flexibility assessments were conducted at baseline and at one, two, and three months post-intervention.
Flexibility was assessed by a modified sit and reach test (in inches) where mothers were instructed to reach forward as far as they could with their hands over each other, over a three-foot ruler, without removing their body from the wall and holding this position for at least two seconds, with greater inches indicating greater flexibility.
次要结局
- Change in Social Support from baseline to 3 months post-intervention(Social support assessments were conducted at baseline and at one, two, and three months post-intervention.)
- Change in Physical Activity Self-Efficacy from baseline to 3 months post-intervention(Physical Activity Self-efficacy assessments were conducted at baseline and at one, two, and three months post-intervention.)
- Change in Fitness Self-Efficacy from baseline to 3 months post-intervention(Fitness Self-efficacy assessments were conducted at baseline and at one, two, and three months post-intervention.)
