Mother's physical activity levels are relatively low, while their energy consumption is generally high resulting in 58% of Australian women over the age of 18 years being overweight or obese. This study aims to confirm if a low-cost, accessible playgroup based intervention program can improve the dietary and physical activity behaviours of mothers with young children.
METHODS/DESIGN: The current study is a randomized controlled trial lifestyle (nutrition and physical activity) intervention for mothers with children aged between 0 to 5 years attending playgroups in Perth, Western Australia. Nine-hundred participants will be recruited and randomly assigned to the intervention (n = 450) and control (n = 450) groups. The study is based on the Social Cognitive Theory (SCT) and the Transtheoretical Model (TTM), and the Precede-Proceed Framework incorporating goal setting, motivational interviewing, social support and self-efficacy. The six month intervention will include multiple strategies and resources to ensure the engagement and retention of participants. The main strategy is home based and will include a specially designed booklet with dietary and physical activity information, a muscle strength and flexibility exercise chart, a nutrition label reading shopping list and menu planner. The home based strategy will be supported by face-to-face dietary and physical activity workshops in the playgroup setting, posted and emailed bi-monthly newsletters, and monthly Short Message Service (SMS) reminders via mobile phones. Participants in the control group receive no intervention materials. Outcome measures will be assessed using data that will be collected at baseline, six months and 12 months from participants in the control and intervention groups.
This trial will add to the evidence base on the recruitment, retention and the impact of community based dietary and physical activity interventions for mothers with young children.

母亲的身体活动水平相对较低，而她们的能量消耗通常较高，导致 58%的 18 岁以上澳大利亚女性超重或肥胖。本研究旨在确认一个低成本、可及的游戏小组为基础的干预计划是否可以改善有年幼子女的母亲的饮食和身体活动行为。
方法/设计：目前的研究是一项针对西澳大利亚珀斯的游戏小组中 0 至 5 岁儿童的母亲的随机对照试验生活方式（营养和身体活动）干预。将招募 900 名参与者，并将其随机分配到干预组（n=450）和对照组（n=450）。该研究基于社会认知理论（SCT）和跨理论模型（TTM），以及包含目标设定、动机访谈、社会支持和自我效能的前行-后行框架。为期六个月的干预将包括多种策略和资源，以确保参与者的参与和保留。主要策略是基于家庭的，将包括一本特别设计的小册子，其中包含饮食和身体活动信息、肌肉力量和柔韧性锻炼图表、营养标签阅读购物清单和菜单计划。家庭策略将得到在游戏小组环境中进行的面对面饮食和身体活动研讨会、定期邮寄和电子邮件双月通讯以及每月通过手机发送的短消息服务（SMS）提醒的支持。对照组的参与者不接受干预材料。将使用从对照组和干预组的参与者在基线、六个月和十二个月收集的数据评估结果测量。
这项试验将增加有关招募、保留和社区为基础的针对有年幼子女的母亲的饮食和身体活动干预的证据基础。
