Project Summary :

Cautionary and emergency procedures such as school closure or nation-wide curfews associated with COVID-19 outbreaks might have influenced lifestyle and quality of life. Therefore, in this project we aim to assess the whole range of health lifestyle behaviors among a representative sample of the Saudi population. We will be subjectively assessing the prevalence and associations of physical activity, sedentary behavior, sleep, dietary habits, stress, and social relationships. A secondary aim is to assess the effectiveness of a behavioral intervention delivered virtually to promote healthy lifestyle practices in people living in area with stay home advisory implemented. It is anticipated that the findings of the present project to provide valuable information about the prevalence and interaction of lifestyle behaviors during COVID-19 enforced cautionary procedures thus helping future studies and health promotion programs in negating any lasting effects.

Project Summary :

The present investigation aims to assess resting metabolic rate (RMR) among Saudi population, including children, adolescents, and adults of both sexes. In addition, this research aims to validate common predictive equations that estimate RMR in underweight, normal, overweight, and obese participants. This cross-sectional investigation will involve at least 400 participants from the community. Anthropometric data are going to be collected and RMR is going to be measured by indirect calorimetry for 20 minutes following an overnight fast. Measurements will be conducted in the Lifestyle and Health Research Center using Metalyzer stationary gas analyzer system (Cotrex, Germany). Common predictive equations such as Harris-Benedict, Mifflin-St Jeor, Owen,et al, and, WHO equations will be validated. Habitual physical activity, sleep and sedentary behaviours are going to be measured using validated questionnaire. Body composition will be assessed using dual-energy X-ray absorptiometry (DXA) and bioelectric impedance analysis (BIA).

Project Summary :

With the increased reliance on technology, electronic communication, heavy use of transportation, and accelerated urbanization, sedentary behaviors are becoming very prevalent globally as well as locally. Prolonged sitting has been associated with cardiovascular diseases risks and increased mortality even while controlling for leisure time physical activity levels. Measurement of sedentary behaviors by objective instruments very costly, requires technical expertise and is very challenging in terms of time and management, especially when testing large groups of people. Currently, there is no validated self-reported instrument in Arabic that can be used to assess sedentary behaviors among adolescents or adults and relate such sedentary activity to social, environmental and health outcomes. Therefore, the main aim of the present research project is to develop an Arabic sedentary behaviors questionnaire along with testing its content, construct and criterion validity as well as examining internal consistency and test re-test reliability. The developmental and testing the psychometric properties of the questionnaire will consist of the following phases: phase 1: constructing the questionnaire’s items, phase 2: testing content validity, phase 3: pre-testing the developed questionnaire, phase 4: testing the internal consistency of the questionnaire’s items, phase 5: testing the construct validity of the questionnaire, phase 6: testing the reliability of the questionnaire, and phase 7: testing the criterion validity of the questionnaire, using activPAL accelerometer as the criterion measure. It is highly anticipated that the developed and validated instrument will be vastly received by local and regional researchers and will hopefully contribute to more understanding of the sedentary activity of the Saudi population and its determinants and associations with social, environmental and health outcomes. The validated sedentary behaviors instrument will also have a significant role in testing any future intervention aimed at reducing sedentary behaviors among Saudi population.

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.
