Body, Soul and Spirit, an adaptation of two evidence-based interventions to promote physical activity and healthy eating among adults in churches in Lagos Nigeria: a three-arm cluster randomized controlled pilot trial.

BACKGROUND

Physical inactivity and unhealthy eating are two leading behavioral risk factors contributing to preventable non-communicable diseases (NCDs). Evidence-based interventions (EBI) using community-engaged approaches to address these risks abound in high-income countries. Comparatively, evidence of such interventions is sparse in low- and middle-income countries, where NCD mortality is greater. This paper describes the protocol for the development of the cultural adaptation and pilot testing of a combination of two EBI (i.e., Body and Soul and the Healthy Body Healthy Spirit), in church-based settings in Lagos, Nigeria. In addition, we describe the development of the inclusion of an additional component, i.e., faith-based text messages, into one of the treatment arms. Our objective is to assess the feasibility of developing and implementing the adapted interventions with the ultimate aim of developing a fully powered trial.

METHODS

This pilot study will assess the design and implementation of a three-arm cluster-randomized pilot trial in 12 randomly selected Anglican churches (4 in each arm). First, we will design a cultural adaptation of the two EBI's to form a multifaceted combined intervention known as the . The second treatment arm, i.e., , will retain all the components of with the inclusion of faith-based text messages using mobile phones. Participants in the control arm will receive information leaflets designed to increase physical activity and healthy food consumption. The outcome measures include participant recruitment and retention, program participation and satisfaction, and data collection completion rates. The outcomes for the proposed definitive trial will be the number of servings of fruit and vegetables and minutes of moderate to vigorous physical activity per day will be assessed at baseline, 3 and 6-month follow-up. Implementation outcomes will be assessed using qualitative and quantitative methods.

DISCUSSION

The study will enhance the understanding of how best to design and implement behavioral interventions in church-based settings using community-based participatory approaches. It will also inform the development of a definitive randomized controlled trial.
