Gender-related differences in the modulation of anthropometric, biochemical, and immune markers by physical activity in hypertensive and diabetic individuals.

Systemic arterial hypertension (SAH) and type 2 diabetes mellitus (T2DM) compose the two major noncommunicable chronic inflammatory diseases. Physical activity has been shown as a promising complementary approach to control the systemic inflammation. However, it is still unclear whether this modulation is gender-dependent. The objective of this study was evaluate the gender-related influence of physical activity on the inflammatory response and biochemical profile of individuals with SAH and T2DM. An international physical activity questionnaire was applied to 376 individuals diagnosed with SAH and T2DM in order to access their exercises routine and was evaluated the influence of physical activity in biochemical, anthropometrical, and immunological markers involved in these disorders in men and women. Even though active individuals have exhibited lower serum levels of IL-1ß, IFN-γ, TNF-α, and IL-17A, the ratios between IL-10 and all inflammatory cytokines were higher in men than in women. Physically active individuals also demonstrated increased HDL/LDL and HDL/VLDL ratios. Moreover, multiple correlations revealed that in active women both IL-10 and TNF-α serum levels positively correlate with fasting glucose levels, and were negatively associated with HDL levels. Our findings suggest that gender-related differences dictate a distinct crosstalk between inflammatory and biochemical markers in physically active individuals.

Regular physical activity reduces the proinflammatory response in older women with diabetes and hypertension in the postmenopausal phase.

Aging in women is characterized by extreme hormonal changes leading them to develop a chronic low-grade inflammation that is linked to the development of systemic arterial hypertension (SAH) and type 2 diabetes mellitus (T2DM). In this scenario, physical activity emerges as an interesting methodology, since it seems to be connected to a decrease in serum levels of some pro-inflammatory cytokines. Nevertheless, most studies evaluate these cytokines in an isolated manner not considering the influence of comorbidities on the responsiveness of participants to the benefits of physical activity. So, this study aimed to assess the influence of physical activity on body composition, anthropometric parameters, lipid profile, and inflammatory markers of diabetic and hypertensive older postmenopausal women. We evaluated 163 women aged from 60 to 80 years, diagnosed with T2DM and SAH that were assisted by the Family Health Units in Vitória da Conquista, Bahia, Brazil. The pratice of physical activity was measured by the International Physical Activity Questionnaire with the participants being classified as active or sedentary individuals. Active older women presented better body composition, lipid profile and inflammatory balance. This was connected to a better correlation profile between these factors in active older women, characteristics that were not noticed in sedentary older women. Moreover, IL-17A and the relationship between IL-10 and the other pro-inflammatory cytokines examined was greatly influenced by physical activity. Consequently, physical activity is linked to a global improvement in T2DM and SAH risk factors and with a positive inflammatory modulation in diabetic and hypertensive older women.

Association between body composition and inflammation: A central role of IL-17 and IL-10 in diabetic and hypertensive elderly women.

In women, aging is evidenced by physiological hormonal alterations that trigger changes in body composition, emergence of chronic low-grade inflammation, which is an important pre-disposition to the development of chronic diseases such as Systemic Arterial Hypertension (SAH) and Type 2 Diabetes Mellitus (T2DM). Although it is a strong pro-inflammatory nature disorder, little is known about how body composition interferes with inflammatory markers in diabetic and hypertensive elderly women. Therefore, this study's objective was to evaluate the inflammation in diabetic and hypertensive elderly women, and their association with fat mass. It comprised the evaluation of 144 women aged between 60 and 80 years old, diagnosed with SAH and T2DM, assisted by Family Health Units in Vitória da Conquista, Bahia, Brazil. According to body mass index (BMI), these women were classified as either eutrophic or overweight. In the eutrophic females, the IL-10 / IL-17A ratio was increased when compared to those overweight. In addition, IL-17 correlated negatively with HDL and positively with total cholesterol, LDL, triglycerides, VLDL, and glucose in the eutrophic ones, but not in the overweight individuals. IL-10 also showed differences in the correlation pattern observed between the groups, since for this eutrophic cytokine, it presented positive correlation with the waist circumference, waist/height ratio, and negative association with IL-17, while in overweight elderly women, it was not observed such pattern. Hence, this work demonstrates how the amount of fat mass interferes with the balance of cytokines, especially IL-10 and IL-17, and how it may exert an effect on biochemical parameters and risk factors associated with T2DM and SAH.
