The effectiveness of an eight-week nutrition and physical activity intervention at a summer camp to prevent obesity, and promote healthy eating habits and physical activity among children in Kuwait was studied. Two summer camps were recruited for intervention and comparison groups. Convenient sampling was used (N= 79). Pretest/post-test assessment were used for the participants in the intervention and comparison groups. Modified Healthy Habits Survey (HHS) was used to measure CHAPTER I: INTRODUCTION Statement of Problem: The prevalence of overweight and obesity has increased rapidly worldwide. Overweight/obesity is defined as having excess body fat that affects the persons health (WHO, 2017). The WHO considers childhood obesity to be a global epidemic (Wang, Wu, Wilson, Bleich, Cheskin, et al., 2013). In Kuwait, the Nutrition Surveillance System (2011) showed that 16% of boys aged 5-9 years and 11% of the girls are obese for the same age group (Alsumaie, 2011). The harsh climate of Kuwait, the abundance and buying power of food and technology have led to an overconsumption of food and sedentary lifestyle, which all contributed to the increase of the prevalence of obesity (Kuwait Nutrition Profile, 2006). Based on the review of the scientific evidence, theWHO developed recommendations to combat childhood obesity. These recommendations are to: 1) promote intake of healthy foods and reduce intake of unhealthy foods and sugarsweetened beverages, 2) promote physical activity and reduce sedentary behaviors, 3) provide a healthy school environment, and nutrition and physical activity education, and 4) provide family-based weight management services for obese children (WHO, 2016). After-school, summer-camps, and childcare programs offer opportunities to deliver these recommendations in a convenient setting for the participants (Kelder, Hoelscher, Barroso, Walker, Cribb, et al., 2005).
