Background: Physical activity can be defined as any movement of the body that requires energy expenditure. This includes any
motion you do through the day excluding sitting still or lying down. For example, walking to class, taking the stairs, mowing the
lawn, and even cleaning your house can be considered physical activity. Exercise is a type of physical activity but not every physical
activity is exercise. Exercise is a planned, structured, and repetitive activity for improving or maintains physical fitness. Physical
inactivity is recognized as one of the leading risk factor for mortality around the world that leads to an estimated 3.2 million deaths
globally. Saudi Arabia has undergone a drastic change in life style and eating habits. Burden of life style related diseases such as
diabetes, coronary artery diseases and hypertension has increased and these diseases are associated with physical inactivity. These
diseases have become the principal cause of morbidity and mortality in Saudi Arabia. Aim of this study: To describe the prevalence
and factors associated with physical activity among adult patients who attend primary health care centers in Makkah city, Saudi
Arabia. Methodology: Cross sectional design will be adopted. The study will be conducted in Makkah city, Saudi Arabia. The present
study was conducted at primary health care centers In Makkah city, Cluster sampling technique was be applied on the three main
sectors inside Makkah city (alzahir, alka'akiah, and ala'adl). Systematic random sampling was be adopted to select persons .The
sample (385) from adult patients aged 18 years and above who will attend primary health care (PHC) centers. Results: the response
rate was (100%) participants, majority of participants are male were (69.00%) while female’s was (31.00%). The majority of our
participants were at overweight and obese (51.0%), a significant relation between BMI and Physical activities Conclusion: Physical
activity likely has a greater role in promoting health in disease populations than previously thought and may confer substantial
reductions in disease burden Primary health care centers in Makkah should be active and able to provide health advice and
behaviour to their patients. There will a strong intention to increase physical activity among physically inactive primary care
physicians (PHCPs). Recommendations: The priority for variables classified as consistently associated with physical exercise should be
to apply these findings to improving interventions. The no modifiable demographic variables suggest subgroups of relatively
inactive adult people that need to be targeted for special intervention programs. Subgroups at risk for being inactive include adult
and children developed to change these variables through education, family programs, or environmental and policy change. Future
research could examine prospectively whether increases in physical activity in unhealthy disease adults lead to a healthier status.
