“…This study showed that 3.3% of the participants were underweight, 68% were normal, 18.2% were overweight, and 10.5% were obese which considered different from the prevalence of underweight, overweight, and obesity among adolescent girls in a study conducted by Silva and colleagues, which were 23%, 10.7% and 3.6% respectively [ 25 ].…”

BACKGROUND:Body weight concern and belief in adolescent females are of great importance. They are the keys to successful dietary interventions including dietary habits’ modifications to practice a healthy diet. This critical phase of transition from childhood to adulthood is the most sensitive stage of behavioural rectification.AIM:This study was conducted with the aim to figure out the prevalence of body image dissatisfaction and the association of body image satisfaction and believe with body mass index in adolescent girls aged 16-18 years.MATERIAL AND METHODS:Two hundred and three Egyptian adolescent females were enrolled in this cross-sectional study. Their mean age was (17.4 ± 0.64) years old. Self-administered questionnaires about the students’ body satisfaction and weight belief were answered by the candidates. Their body mass index was calculated. Also, sociodemographic data were collected. Data were analysed using SPSS software version 16.0. Chi-square test was conducted for the variables.RESULTS:Sixty-eight percent of the students were within normal weight, 3.3% were underweight, while 18.2% and 10.5% were overweight and obese respectively. Body dissatisfaction was prevalent among 37.4%. The prevalence of body dissatisfaction was higher in both obese and underweight candidates reaching (93.8% and 80%) respectively. This reflects students’ awareness of their body shape.CONCLUSION:More than one-third of adolescent females were dissatisfied with their body image. The subjective belief about self-body image matched the objective Body Mass Index measurements.

“…These cut-offs are based on studies involving Western populations. According to this cutoff, the prevalence of obesity (≥30) is only 2–4% in Asian populations [ 22 ], while in young Brazilian adults the prevalence of obesity is 8.1% (males) and 10.7% (females) [ 23 ]. In addition, only genotype 1b patients were included in the Japanese cohort while in this study, genotypes 1a, 1b, and 3 were included that may have contributed to the differences in results.…”

The role of hepatitis C virus (HCV) in insulin resistance (IR) is not fully understood. The aim of this study was to determine the impact of amino acid (aa) substitutions in the core region of HCV according to IR and to identify clinical and laboratory associations. Ninety-two treatment-naive HCV patients were recruited to determine laboratory data and blood cell count. IR was determined using Homeostasis Model Assessment (HOMA) index where IR was defined as HOMA ≥2. HCV RNA load and genotype were determined by Abbott Real time HCV. HCV core region was determined by direct nucleotide sequencing. Bivariate analysis was conducted using HOMA IR ≥2 as a dependent factor. IR prevalence was 43.5% (n = 40), vitamin D sufficiency was found in 76.1% (n = 70) and 72.8% (n = 67) had advanced liver fibrosis. In the bivariate analyses, elevated values of γGT (p = 0.024) and fibrosis staging (p = 0.004) were associated with IR, but IR was not related to core mutations. The presence of glutamine in position 70 was associated with low vitamin D concentration (p = 0.005). In the multivariate analysis, no variable was independently associated with HOMA-IR. In conclusion, lack of association between IR and HCV core mutations in positions 70 and 91 suggests that genetic variability of this region has little impact on IR.
