The purpose of this study is to determine the effect of social media on body weight and eating behaviour in housewife versus worker postmenopausal women.

Menopause altered fat distribution that occurs as negative impacts of the increase in insulin resistance, and the incidence of diabetes has risen exponentially. This increase, in turn, has been translates into an increased risk of cardiovascular disorder (CVD) and death, with the impact being greater in women than in men.

Media has been largely implicated in the widespread incidence of disordered eating worldwide. One of the main theories to explain the relationship between media and disordered eating is the sociocultural model. According to sociocultural theory, when young women are exposed to idealized body images in the media, they internalize these images gradually developing unrealistic body image expectations. In turn, failure to attain this idealized body image may result in body shape concerns, body dissatisfaction, and disordered eating behaviors.

Social media users are often exposed to advice and recommendations on diet and health issues through books, journals and electronic formats supported by a quick exchange of ideas through social media without scientific basis. The constant infiltration of social media into our life has necessitated a research on the effects of it on eating behavior. Owing to the prevalence of social media use, including the sharing photographs and making comments to foods, menus and recipes, it is especially important to identify the potential effects of these issues on eating behaviors.

People who use social media more are at greater risk of sleep disturbance that leads to obesity. It was reported that 40% decrease in weight gaining accrued in people who limits their screen-time than in people without such limitation.

There is widespread theoretical and practical interest in understanding how social media affect health related behaviours. Large observational studies of population health have discussed the effect of social media effect on human health even its benefits or hazards.

Previous studies illustrated the link between the time spent at social media and the resulted weight among young generations and adults, but to our knowledge, there is no previous study investigated the effect of social media on weight and eating behaviour among postmenopausal women or compared between workers and housewife postmenopausal women as regard to time spent on social media. So, this study will be the first one in this issue. Therefore, this study will be of valuable benefits and increased body knowledge of physical therapists in scientific field.
