AbstractIntroduction: Adherence to weight loss plan is critical for successful weight loss and maintenance. However, adherence level and factors predicting adherence were seldom explored. This study investigated psychosocial predictors of one-month adherence to a community-based Lifestyle Modification Program (LMP) among Chinese overweight and obese adults.

Methods: 266 Chinese overweight and obese adults newly enrolled in LMP for at least 4 weeks were recruited. 207 completed baseline and one month follow up (78.3% Female, mean age 38.90±10.42, BMI 28.32±4.17, body weight 74.46±14.10, 59.4% had attained at least tertiary education). Indicators of one-month adherence included diet adherence score (continuous), physical activity (PA) adherence score (continuous), attendance (dichotomous), and self-monitoring level (dichotomous). Multivariate analyses were used to identify which psychosocial predictors (perceived support, knowledge, self-efficacy, motivation and stage of change) at baseline and one-month were associated with one-month adherence with adjustment for baseline BMI, age, sex, education and income.

Results: No significant psychosocial factors was identified for attendance. Multiple logistic regression suggested one-month diet stage of change as an independent predictor of diet self-monitoring level. Multiple
linear regression suggested one-month nutrition knowledge as an independent predictor of diet adherence
score while one-month PA self-efficacy and PA stage of change as independent predictors of PA adherence score.

Conclusions: Diet stage of change, nutrition knowledge, PA self-efficacy and PA stage of change were signficant
predictors of adherence to LMP at one month. The effect of psychosocial factors on adherence differs among indicators of diet adherence score, PA adherence score, attendance and self-monitoring level.
