Obesity is characterized by an alteration in body composition (BC); however, it is not known whether this alteration is modified by aging or sex. The aims of this study were to analyze BC in individuals with obesity based on age and sex and to determine the prevalence of sarcopenia. Seven hundred and fifty-five obese individuals were subdivided into four age groups. The hole (WB) and segmental BC were determined using dual-energy X-ray absorptiometry (DXA). In men, the WB lean tissue mass (LTM) and fat mass (FM) adjusted by weight and height were relatively constant with age. In women, the WBLTM was higher and WBFM was lower in the >65 group compared to the 18–34 group. A decrease in the LTM and FM at lower limbs and an increase in the trunk were observed, particularly in women, inducing a lower appendicular lean mass index (ALMI; appendicular LTM/height2) in the >65 group compared to the 18–34 group in both sexes. This study demonstrated that even though the WBLTM and FM are relatively constant with age, individuals with obesity present a localized redistribution of these two components. This body composition change leads to a decrease of the ALMI with age, one of the criteria included in the sarcopenia definition.

Background: Pakistan has the second highest prevalence of hepatitis C in the world after Egypt. Viral hepatitis is a leading cause of morbidity and mortality in Pakistan and, worryingly, reinfection rates are also on the rise. This cross-sectional study was aimed at finding the most common genotypes of hepatitis C in terms of age and sex in a Pakistani cohort. Materials and methods: The authors collected blood samples from 1,260 patients with diagnosed hepatitis C visiting a primary teaching hospital affiliated with Peshawar Medical College, Pakistan, from different districts of Khyber Pakhtunkhwa, Pakistan, between January 2017 and April 2019. Hepatitis C virus RNA was quantified by real-time polymerase chain reaction and genotyping was then performed. Results: The authors found that genotype 3a was the most prevalent type followed by 1a, mixed, and 3b, respectively. Genotypes 2a and 1b were the least prevalent in Khyber Pakhtunkhwa. The most common genotype was 3a, observed in 75.87% of cases. The most common mixed genotype was 3a+1a, observed in 39 cases (3.10%); it had a prevalence of 3.49% in females compared with 2.70% in males. Overall, the most common age group affected by hepatitis C virus was 41–50 years (31.35%), followed by the 51–60 years group (24.45%). Infection rate was comparatively low in other age groups. A significant difference was observed in the prevalence of genotype 3a and 2a among different districts. Conclusion: The authors concluded that genotype 3a was the most prevalent genotype and it was observed more frequently in the female population, with a median age of 45 years.

 Objectives: The objectives of the study were to compare the health knowledge of women of different age groups. To evaluate different methods for developing health literacy.Methods: A cross-sectional study was conducted from December 2014 to January 2016 in Baghdad, Iraq. All candidates were females, age ≥18 years, neither medical staff nor medical students.The sample was divided into two groups: Group A: Females aged18–45 years, Group B: Females aged >45 years. A comparison between the two groups regarding their health literacy and the source of information was made.Results: The final sample included 213 women, of them, there were 107≤45 years (Group A) and 106>45 years (Group B) women. Significant difference was found between both groups regarding the knowledge about the prevention of cholera where the accurate answers were 46.7% in Group A versus 80.1% in Group B. The main source of information for both groups was the personal experience. However, internet was used more (42%) by the younger women (Group A), and television was used more (52.8%) by the older women (Group B).Conclusion: Young women had a better literacy on common medical problems, but the old showed overall limited health literacy. Pharmacists, physicians, and activities of the Ministry of Health played an impotent role in health literacy in the old women.

To determine whether the age-related reduction in basal metabolic rate (BMR) is explained by a quantitative and/or qualitative change in the components of lean tissue, we conducted a cross-sectional study in groups of young ( n = 38, 18–35 yr) and older ( n = 24, 50–77 yr) healthy individuals. BMR was measured by indirect calorimetry. Body composition was obtained by using dual-energy X-ray absorptiometry (DEXA), which permitted four compartments to be quantified [bone mineral mass, fat mass (FM), appendicular lean tissue mass (ALTM), and nonappendicular lean tissue mass (NALTM)]. Absolute BMR and ALTM were lower, whereas FM was significantly higher in the older, compared with young, subjects. BMR, adjusted for differences in FM, ALTM, and NALTM, was significantly lower in the older subjects by 644 kJ/day. In separate regression analyses of BMR on body compartments, older subjects had significantly lower regression coefficients for ALTMand NALTM, compared with young subjects. Hence, the age-related decline in BMR is partly explained by a reduction in the quantity, as well as the metabolic activity, of DEXA-derived lean tissue components.

In adolescence, health status is influenced by several factors, including dietary pattern and physical activity (PA) which are crucial elements of lifestyle in terms of prevention and treatment of metabolic and chronic diseases. The current study aimed to explore the impact of the different intensity levels of PA along with the adherence to a Mediterranean diet (MD), on body composition indices and metabolic parameters in a cohort of adolescents, thereby investigating potential predictors of health behavior in youth. This cross-sectional study was carried out among 92 participants (44 girls and 48 boys, aged 14 to 17 years), which were divided into the following three groups according to intensity levels of PA: Group A (physical inactivity), Group B (moderate PA), and Group C (vigorous-intensity PA). The Questionnaire of Adherence to the Mediterranean Diet (KIDMED test) was used to assess both diet composition and adherence to a MD. All subjects underwent anthropometric measurements, bio-impedentiometric analysis for body composition parameters, and biochemical and hormonal measurements. The majority of adolescents (60.87%) had a medium adherence to the MD, and even a better distribution of food rates was found in adolescents performing vigorous-intensity PA. A comparison of anthropometric measurements and body composition parameters among groups showed that body mass index and fat mass (FM) were significantly lower while body cell mass (BCM), free fat mass (FFM), phase angle (PhA), and total body water (TBW) were higher in Group C adolescents as compared with those of Group A. In Group C, insulin resistance (HOMA-IR) was reduced and insulin levels were inversely associated with FFM (r = −0.454 and p = 0.004) and directly correlated with FM (r = 0.331 and p = 0.003). In the same Group C, we observed elevated serum irisin levels and lower lipid profile markers as compared with Group A. Interestingly, irisin negatively correlated with both total cholesterol (r = −0.428 and p = 0.04) and LDL (r = −0.468 and p = 0.02) in Group C. Finally, a receiver operator characteristic curve (ROC) analysis revealed irisin, LDL, HDL, and body composition variables (FFM, BMC, PhA, and TBW) as the most predictive measures for vigorous-intensity PA. Our results highlight the importance of developing healthy lifestyle programs that include improving the intensity of PA among a young population as a superior strategy for ensuring a better quality of life.

History Of

This study assessed differences in bone-mineral density (BMD) and lean and fat tissues between 5 age groups of White men age 65–93 years. Lean and fat tissues were measured with absorptiometry and anthropometry, and BMD, with dual-energy X-ray absorptiometry. Forearm, spinal, and femoral T scores were used to classify BMD as normal, osteopenic, or osteoporotic. A questionnaire evaluated previous physical activity, calcium intake, and bone fractures. Significantly lower values in body weight, lean tissue, and forearm BMD occurred in the older age groups. Significant, positive relationships were found between total lean tissue and radial, spinal, and hip BMDs. For the total group, osteopenic and osteoporotic T scores, respectively, were femoral neck 70.6% and 9.8%, radius 27.5% and 25.5%, and spine 25.5% and 7.8%. Differences in BMD values were found between levels of lifestyle factors (dietary calcium and history of previous fractures). In conclusion, elderly men should be encouraged to maintain adequate total lean tissue because of its association with BMD.
