Overweight and obesity are a serious public health problem globally. Healthcare workers in some countries have been reported to be having a high prevalence of being overweight despite them being well informed of the aetiology and risks of excessive body weight. However, the problem of being overweight and obese among Malaysian healthcare workers is still poorly understood. The aim of this study is to assess the prevalence and factors associated with overweight and obesity among healthcare workers in Pejabat Kesihatan Daerah (PKD) Melaka Tengah.
