The aim was to assess the feasibility and preliminary efficacy of a community-based physical activity (PA) intervention targeting mothers and daughters.
A randomized controlled trial of 48 primary school-aged girls and their 40 mothers were randomized to (i) Mothers And Daughters Exercising for Life (MADE4Life) (n = 21 mothers, n = 25 daughters) or (ii) wait-list control (n = 19 mothers, n = 23 daughters). The 8-week program involved 8 sessions; 25-minute separate mothers and daughters education sessions and 60-minutes PA together. Assessments were at baseline, postintervention and 3-month postintervention. Primary outcome measure was daughters' moderate-to- vigorous physical activity (MVPA) (accelerometer). Secondary outcomes included accelerometer-assessed light/moderate/vigorous PA, BMI, waist circumference, body composition, blood pressure, resting heart rate, sedentary behaviors and mothers' self-reported PA, parenting measures, and cognitions. Intention-to-treat analysis used linear mixed models.
Recruitment and retention goals were exceeded. Attendance rates, program acceptability and satisfaction were high. There was no significant group-by-time effect for daughters' %MVPA (-0.08; 95%CI -1.49, 1.33, d = -0.03) or other secondary outcomes for girls (postintervention range d = 0.01 to -0.46). Significant intervention effects were found for mothers' %VPA (P = .04, d = 0.25) and role modeling (P = .02, d = 0.66).
MADE4Life was both feasible and acceptable. Although very small effect sizes were found for the daughters, significant changes were seen for mothers (d = 0.25 to 0.66). Future fully powered trials targeting PA in mothers and daughters is warranted.
目的是评估一项针对母亲和女儿的社区体育活动(PA)干预措施的可行性和初步效果。
一项随机对照试验,将48名小学适龄女孩及其40名母亲随机分为两组:(i)母女终身锻炼(MADE4Life)组(21名母亲,25名女儿)或(ii)等待名单对照组(19名母亲,23名女儿)。为期8周的项目包括8次课程;25分钟的母亲和女儿单独教育课程以及60分钟的共同体育活动。评估在基线、干预后和干预后3个月进行。主要结局指标是女儿的中度至剧烈身体活动(MVPA)(加速度计测量)。次要结局包括加速度计评估的轻度/中度/剧烈身体活动、BMI、腰围、身体成分、血压、静息心率、久坐行为以及母亲自我报告的身体活动、育儿措施和认知。意向性分析采用线性混合模型。
超过了招募和留存目标。出勤率、项目可接受性和满意度都很高。女儿的MVPA百分比(-0.08;95%CI -1.49,1.33,d = -0.03)或女孩的其他次要结局在组间随时间变化无显著差异(干预后d值范围为0.01至-0.46)。母亲的VPA百分比(P = 0.04,d = 0.25)和榜样作用(P = 0.02,d = 0.66)有显著干预效果。
MADE4Life既可行又可接受。虽然女儿们的效果量非常小,但母亲们有显著变化(d = 0.25至0.66)。未来有必要针对母亲和女儿的身体活动开展充分有力的试验。
