BACKGROUND: Gestational diabetes mellitus (GDM) is one of the common complications that occur during pregnancy. Early intervention is essential to prevent the development of the disease in the nonpregnant state but also helpful in preventing the occurrence of GDM. The aim of the study was to assess the effect of aerobic exercises on insulin sensitivity and fasting plasma glucose level in pregnant women with risk for gestational diabetes mellitus. MATERIALS AND METHODS: Forty multigravidae women between 20-24 weeks of gestation with risk for GDM were randomly selected (age range was 25-35 years), body mass index ranged from 30-35 kg/m². Women were divided into two equal groups: intervention group (A), which followed an aerobic exercise program in the form of walking on treadmill, three times weekly until the end of 37 weeks of gestation in addition to diet control. Control group (B) which received diet control with usual care given by obstetricians and midwives. Evaluation of the women in both groups was carried out before and after treatment program through assessment of fasting blood glucose and insulin levels. RESULTS: There was a highly statistically significance decrease in fasting blood glucose level, fasting insulin level in both groups where the p value was 0.0001 favoring group (A). CONCLUSION: Moderate intensity of aerobic exercises were effective in reducing fasting blood glucose level and fasting insulin level in pregnant women with risk for gestational diabetes mellitus.
[Purpose] The present study investigated the relationships of physical activity and
healthiness with the intelligence quotients of high school students in Jeddah. [Subjects
and Methods] A total of 135 male and female students were randomly drawn from public and
private secondary schools in Jeddah. A self-designed questionnaire was distributed to the
students that included demographic, physical activity, and health status sections. Body
mass index measurement and an intelligence quotient test were carried out for all
students. In addition, samples of blood were collected to estimate hemoglobin and serum
iron. [Results] The highest proportions of males and females (39.1% and 51% respectively)
had an intelligence quotient score of more than 75%. Moreover, the findings revealed that
about 35% of the students were categorized as overweight obesity, and there was aninverse
correlation between body mass index and physical activity. Students who shared physical
education classes and exercising at and outside school showed a positive correlation with
high IQ scores. Regarding hemoglobin and iron levels, there were significant correlations
between their levels in blood and IQ. [Conclusion] The intelligence quotient of adolescent
students is positively associated with physical activity and health status.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
