AbstractPurpose: The aim of this review is to provide an overview of factors associated with adherence to lifestyle modification programs among overweight and obese adults.

Methods: An electronic search was conducted using PubMed, Medline, PsycINFO and PsycARTICLE to identify prospective studies that examined the factors of adherence to lifestyle modification program. We included studies with clearly defined adherence indicators, components of healthy diet, physical activity and behavioural strategies or theories, with weight management as one of the aim of the studies, explored the association between factors and adherence outcomes, included adults aged 18 – 64 and written in English. We excluded studies that were pharmacological or surgical in nature, involved meal replacement, low calorie diet or very-low-calorie diet and included participants with existing chronic diseases, significant psychological comorbidities or any medical condition that limited the ability to perform PA. In total, we included 19 studies published between 2004 and 2016.

Findings: Four adherence indicators were identified among the 19 studies. The most commonly used indicator was attrition, followed by attendance, self-monitoring and dietary adherence. A wide array of factors has been studied but only few studies exploring each factor. The identified factors were categorized into four groups (psychosocial factors, socio-demographic factors, behavioural factors and physical factors) and presented in descending order of popularity. Limited evidence suggested being in action or maintenance stage of change at baseline, older age, higher education, healthier eating and physical activity behaviours and higher initial weight loss may predict better adherence. However, having depression, stress, strong body shape concern, more previous weight loss attempts and being unemployed may predict poor adherence. Inconsistent findings were reported for self-efficacy, motivation and gender.

Conclusions: Identification of the factors associated with adherence could provide direct implication for program improvement that facilitate and maintain health behavioural changes. In light of the scare evidence on factors of adherence identified, more rigorous studies are warranted to enhance our knowledge in this area. In particular, further research should focus on the behavioural aspects of adherence such as dietary and physical activity adherence
