Project Summary :

Negative lifestyle behaviors such as physical inactivity, sedentary behavior, unhealthy dietary habits, insufficient sleep, and stress mature during emerging adulthood. Furthermore, these behaviors have been shown to be associated with increased risk of disease incident and mortality. However, the clustering prevalence and effect of these behaviors is poorly understood. Therefore, in this project we aim to assess the whole range of health lifestyle behaviors among Princess Nourah bint Abdulrahman University students. We will be subjectively and objectively assessing the prevalence and associations of physical activity, sedentary behavior, sleep, dietary habits, stress, and social relationships. It is anticipated that the findings of the present project to provide valuable information about the prevalence and interaction of lifestyle behaviors and any potential areas of need for health promotion programs.

Project Summary :

The prevalence of pediatric obesity has risen alarmingly across both developed and developing countries in recent years. In Saudi Arabia, pediatric obesity is becoming prevalent and the recent transition in lifestyle with associated changes in nutrition have largely contributed to the increase in obesity prevalence observed among Saudi children and youth. Therefore, the aim of the present research project is to investigate the complex associations between lifestyle behaviors, sociodemographic characteristics, children’s quality of life, body image, self-esteem, and home and built environment of obese children and their parents with children’s anthropometric, cardiovascular, respiratory, endocrine, and metabolic functions. Comprehensive baseline data will be collected from overweight and obese children and adolescents and their family and compared with a group of normal weight children and adolescents. We will also be looking into different interfamilial associations and differences between children and adolescents with and without obesity. The study sample will include all overweight or obese children and adolescents (250 participants), from the obesity clinic at King Abdullah Bin Abdul-Aziz University Hospital (KAAUH) as well as their parents along with 120 healthy non-overweight non-obese children and adolescents from the pediatric clinic in KAAUH and nearby community. Ethical permission will be sought from IRB at PNU. The following extensive variables are going to be assessed and studied: anthropometric measurements, skeletal maturation, body composition measurement, blood pressure, resting metabolic rate, maximal cardiopulmonary function, blood lipids, fasting glucose, hemoglobin A1c, insulin resistance, resting heart rate and heart rate variability, central pressure and pulse wave velocity, physical activity levels, sedentary behaviors, sleep patterns, dietary intake, vitamin D level, muscular strength and flexibility, bone density, child’s quality of life, body image perception, self-esteem, and home and built environment. Also, will be included the following biomarkers: leptin, ghrelin, adiponectin, Peptide YY, brain-derived neurotrophic factor, inflammatory markers IL-6, CRP and FTO gene. It is expected that the findings of the present study will provide valuable data on obesity correlates and determinants among Saudi children and adolescents, which will have significant implications for the health and well-being of Saudi children and youth. Such important information can be used effectively for planning and executing children’s health promotion programs, weight control strategies and lifestyle interventions.

Project Summary :

The aim of the present project is to investigate the associations of body image perception, obesity, physical activity, sedentary behaviours and dietary habits among young adult females attending fitness centers in Riyadh. A stratified cluster random sample is going to be used to select 400 young adult females from all female fitness centers in Riyadh. Age, body weight, height, body mass index (BMI) and socioeconomic status will be assessed. A valid self-reported questionnaire will also be used to assess physical activity, sedentary behaviours, sleep duration and dietary habits. In addition, Stunkard Figure Rating Scale (FRS) with 9 silhouettes figures will be used for body image (shape) assessment, including perceived and desired body images. The findings of the current study have some implications upon the influence of lifestyle habits that have on body weight and body image perception. Indeed, accurate perception is critical for individuals engaging in weight loss and maintenance. Such findings are expected to contribute to our knowledge on the associations of young adult female’s weight status, body shape misperception, lifestyle behaviours and well-being. This is an important step when addressing and preventing women obesity in Saudi Arabia.


Project Title:

Lifestyle behaviors and dietary habits of Saudi adolescents living in Riyadh: Revisited after a ten-year period

PI: Prof. Hazzaa M. Al-Hazzaa

Co-PI: Nada M. Albawardi PT, MPH

Project Summary:

In 2009, a group of Arab researchers, including those from Saudi Arabia, initiated the Arab Teens Lifestyle Study (ATLS). The main findings of ATLS data that was collected from Saudi Arabia indicated that Saudi adolescents 15-19 years old had high prevalence of overweight plus obesity, increased physical inactivity and sedentary behaviours, insufficient sleep and unhealthy dietary habits. The findings have also identified several lifestyle factors associated with obesity among Saudi adolescents. By next year, there will be a ten years span from the past ATLS data collected on adolescents living in Riyadh. Therefore, the present research project intends to revisit the lifestyle behaviours and dietary habits of Saudi adolescents living in Riyadh city and examine the trend of such lifestyle behaviours research design, methodologies and instruments that were used in 2009. Making comparison between the two cohorts provides indirect evidence on the changes in the Saudi adolescents’ lifestyle behaviours that have occurred over the course of 10 years.
