Aim To identify predictors of initial weight loss among women with abdominal obesity by using a path model. Background Successful weight loss in the initial stages of long‐term weight management may promote weight loss maintenance. Design A longitudinal study design. Methods Study participants were 75 women with abdominal obesity, who were enrolled in a 12‐month Community‐based Heart and Weight Management Trial and followed until a 6‐month assessment. The Weight Efficacy Lifestyle, Exercise Self‐Efficacy and Health Promoting Lifestyle Profile‐ II measured diet self‐efficacy, exercise self‐efficacy and health‐promoting behaviour respectively. All endogenous and exogenous variables used in our path model were change variables from baseline to 6 months. Data were collected between May 2011–May 2012. Findings Based on the path model, increases in both diet and exercise self‐efficacy had significant effects on increases in health‐promoting behaviour. Increases in diet self‐efficacy had a significant indirect effect on initial weight loss via increases in health‐promoting behaviour. Increases in health‐promoting behaviour had a significant effect on initial weight loss. Conclusion Among women with abdominal obesity, increased diet self‐efficacy and health‐promoting behaviour were predictors of initial weight loss. A mechanism by which increased diet self‐efficacy predicts initial weight loss may be partially attributable to health‐promoting behavioural change. However, more work is still needed to verify causality. Based on the current findings, intensive nursing strategies for increasing self‐efficacy for weight control and health‐promoting behaviour may be essential components for better weight loss in the initial stage of a weight management intervention.
