School- and Family-Based Lifestyle Programme for Primary School Children in Punjab, Pakistan: A Feasibility Study

6 ноября 2026 г. обновлено: Qin jiabi, Central South University

A School- and Family-Based Lifestyle Programme for Primary School Children in Punjab, Pakistan: A Feasibility Cluster Non-Randomised Controlled Trial

The goal of this feasibility study was to find out whether a larger trial of a school- and family-based lifestyle programme for primary school children in Punjab, Pakistan, can be carried out successfully. The programme aims to help children aged 7 to 11 years eat more healthily, be more physically active and sleep well, in order to prevent unhealthy weight gain.

The main questions it aimed to answer were:

  • Will schools and families agree to take part, and will children stay in the study until the end?
  • Can measurements and questionnaires be completed fully and within a reasonable time?
  • Can the programme be delivered in schools as planned, and will children and parents attend the sessions?

Ten primary schools in three districts of Punjab (Lahore, Sahiwal and Bahawalnagar) took part. Children in five schools received the 17-week programme, and children in the other five schools continued their usual school routine.

Children in the programme schools:

  • attended a weekly classroom session about healthy eating, physical activity and sleep
  • took part in extra physical activity at school
  • kept a weekly activity diary at home

Their parents were invited to group sessions and two individual meetings, and received printed guidance.

In all schools, children's height, weight, waist size and blood pressure were measured, and children and parents completed questionnaires at the start of the study and after 18 weeks.

Подробное описание

This was a feasibility cluster non-randomised controlled trial. Schools were the unit of allocation: five of the seven schools able to timetable the programme in the spring term received the intervention, and five schools served as controls. To minimise contamination, schools in different groups were at least 3 km apart, served separate catchment areas and shared no teaching staff.

The programme was grounded in the socio-ecological model and targeted children (classroom education, school physical activity and self-monitoring), families (parent group sessions, individual meetings and printed guidance) and schools (daily physical activity opportunities). During Ramadan, school physical activity was suspended and session timing was adjusted.

The standard deviation of change and the intracluster correlation coefficient of BMI-for-age z-score (WHO 2007 reference) were estimated to inform the sample size of the definitive cluster randomised trial. Initial between-group differences in weight status, blood pressure and behaviours were estimated with linear mixed models including a random intercept for school, adjusted for baseline value, age, sex and district.

Экспериментальный: Lifestyle programme

Children in grades 3-5 and their parents in five primary schools received the 17-week school- and family-based lifestyle programme.
Поведенческий: School- and family-based lifestyle programme

A 17-week programme with two components. Child component: 16 weekly 40-minute classroom sessions on healthy eating, physical activity and sleep, each followed by a take-home task; a target of 45 minutes of school physical activity (physical education, classroom activity breaks and after-class sport) on every school day; and weekly self-monitoring with a home exercise diary and self-weighing, with private feedback every four weeks. Parent component: nine 60-minute group sessions paralleling the child curriculum, two individual meetings on the child's growth and behaviour goals, and printed guidance on screen time, family activity, healthy eating and sleep. During Ramadan, school physical activity was suspended and session timing was adjusted.
Без вмешательства: Usual practice

Children in five primary schools continued their usual school timetable, including two 35-minute physical education periods per week, and received no study activities. Programme materials were provided to these schools after the study.
