Pregnancy is a significant phase in women's lives, marked by psychological, biological, and emotional changes. It lasts for approximately nine months and is divided into three trimesters. Identifying risk factors such as maternal age, gestational age, ethnicity, and lifestyle habits is crucial for managing pregnancy effectively. Anxiety, depression, and stress can significantly impact pregnancy-related responsibilities and overall well-being, making collaboration with a multidisciplinary healthcare team essential. Physical activity during pregnancy offers numerous benefits, including better physical fitness, improved psychological health, weight management, and reduced risk of gestational diabetes. However, studies show that many women are not sufficiently active, particularly in the first trimester, where activity levels tend to be lower. Regular monitoring of thyroid function (TSH levels) and liver enzymes (ALT, AST) is essential to avoid complications, as pregnancy can affect thyroid function and liver health. Additionally, monitoring hemoglobin and hematocrit levels is necessary to manage pregnancy anemia. The proposed study aims to evaluate healthy lifestyle behaviors, physical activity, and biochemical markers among pregnant women in the first trimester, using various questionnaires and laboratory tests. This study will provide valuable insights into maternal health and guide clinical practices during early pregnancy to reduce complications and enhance overall outcomes.
