Background: Obesity-induced inflammation may independently disturb the function of critical organs such as liver. This study aimed to investigate the association of obesity with serum levels of biomarkers of liver function including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) in adult women. Methods:This cross-sectional study was carried out on 360 adult women in the summer of 2020 in Tehran, Iran. The participants were categorized into two groups based on their body mass index (BMI≤29.9 and BMI > 30). The serum levels of ALT, AST, ALP How to cite this article: Jalili V, Poorahmadi Z, Hasanpour Ardekanizadeh N, et al. The association between obesity with serum levels of liver enzymes, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gamma-glutamyl transferase in adult women.

BackgroundThe association between breast cancer (BC) and different indices of dietary fats has not been well-studied. Thus, this study aimed to investigate the association between BC and dietary fat quality (DFQ) indices in Iranian women.MethodsThis case–control study was conducted on 120 women with breast cancer and 240 healthy women in Tehran, Iran. Food Frequency Questionnaire and nutritionist IV software were used to assess the intake of dietary fats and to calculate the DFQ indices.ResultsThe patients with BC had a higher total fat (TF) (P < 0.01) and a lower ratio of polyunsaturated fatty acids (PUFAs) omega-3 to PUFAs omega-6 (ω-3/ω-6) compared with the controls (P < 0.001). TF had a significant association with BC risk (OR: 1.16; 95% CI: 1.01–1.33, P < 0.001). No significant association was found between BC and PUFA/saturated fatty acid ratio or the ω-3/ω-6 ratio.ConclusionThe patients with BC had a lower ω-3/ω-6 ratio and a higher total dietary fat intake than the healthy women. Total dietary fat intake was also directly associated with the risk of BC. Thus, low-fat diets may have beneficial effects for BC prevention. Further longitudinal studies are warranted.

Background: Dyslipidaemia is a group of abnormalities that predispose people to heart disease. The index of nutritional quality (INQ) is a tool for qualitative and quantitative nutritional assessment, which has special significance in assessing clinical nutritional problems. The objective of this study was to determine the association between the INQ and lipid profile in adult women.Methods: This was a cross-sectional study on 360 healthy women referring to the nutrition clinic of Shohadaye Tajrish hospital, Tehran, Iran. Calorie and nutrient intake were assessed using a validated food frequency questionnaire. The amount of physical activity was estimated using a validated International Physical Activity Questionnaire. To measure serum lipid levels, 5 ml of venous blood samples was taken from the participants. Results:The results showed a negative association between total cholesterol and the INQ of niacin (B = −0.110, p = .02) and between high-density lipoprotein cholesterol with the INQ of biotin (B = −0.119, p = .01). Also, a positive association was found between triglyceride and the INQ of B6 (B = 0.096, p = .04). The results remained
