Abstract Objective The association between the Mediterranean diet (MED) and the dietary approach to stop hypertension (DASH) with some mental disorders is well-documented. However, a consistent relationship with young adults as a vulnerable population has yet to be known. Therefore, we aimed to investigate the relation between Iranian young male adults’ mood and happiness state with DASH/MED patterns. Results Participants’ mean age was 23.65 ± 1.74 years, within the age range of 18–28 years, and their BMI was 24.23 ± 3.82 kg/m². After adjusting for all covariates, those in the highest DASH tertile had 54% lower odds of poor mood compared to the lowest tertile (OR = 0.46; 95%CI: 0.24, 0.88). An inverse relationship was also found between DASH and low happiness scores (OR T3 vs. T1 = 0.51, 95%CI: 0.27, 0.96). No significant association was found between MED and mood or happiness. Therefore, results showed that participants who adhered more closely to the DASH diet were less likely to report being unhappy or having a poor mood. Further prospective studies are required to confirm these findings.

BackgroundOsteoporosis is a chronic condition characterized by reduced bone strength and an elevated risk of fractures. The influence of diet and glucose metabolism on bone health and the development of osteoporosis has been an area of interest. This study aimed to investigate the potential association between dietary glycemic index (DGI), dietary glycemic load (DGL), dietary insulin index (DII), dietary insulin load (DIL), and the odds of osteoporosis among Iranian adults.MethodsData from 12,696 Iranian teachers (35–50 years) in a cross-sectional study on diet, nutrition, physical activity, and diseases were analyzed. The participants had no history of diabetes, cardiovascular diseases, stroke, thrombosis, or cancer and consumed between 800 and 4,200 kcal/day. We estimated DGI, DGL, DII, and DIL from a validated semi-quantitative food-frequency questionnaire (FFQ). We also diagnosed osteoporosis using dual-energy X-ray absorptiometry.ResultsIn the fully adjusted model, higher DGI and DGL were significantly associated with increased odds of osteoporosis (OR = 1.78 and 1.46 for the highest vs. the lowest tertile; P trend < 0.05). Nonetheless, no significant association was found between DII or DIL and osteoporosis prevalence. Moreover, higher DIL and DGL were associated with a higher intake of calorie-dense/nutrient-poor foods and a lower intake of antioxidant-rich foods.ConclusionAlthough our study showed that high DGI/DGL increased osteoporosis risk in Iranian teachers, no association was found between DII/DIL and osteoporosis prevalence. More research is needed to confirm these results and understand the mechanisms involved.

Objective: The association between the Mediterranean diet (MED) and the dietary approach to stop hypertension (DASH) with some mental disorders is well-documented. However, a consistent relationship with young adults as a vulnerable population has yet to be known. Therefore, we aimed to investigate the relation between Iranian young male adults' mood and happiness state with DASH/MED patterns.

Background: Anthropometric studies in children and adolescents are important to screen changes in growth and puberty. Hence, standard percentiles and cutoffs are set by the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and Iranian national criteria. This study aimed to examine and compare the prevalence of weight disorders in children and adolescents in Lorestan province according to different criteria. Methods: Children and adolescents (6–18 years) were randomly selected from the urban and rural areas by the multistage stratified cluster sampling method. All Iranian citizens aged who resided in Lorestan province for at least one year were eligible to participate in this study. After obtaining consent forms, researchers gathered the accurate anthropometrics and body mass index (BMI) measurements. Results: A total of 866 children and adolescents took part in the study, 447(51.6%) of whom were girls and 419 (48.4%) were boys. The overall prevalence of overweight and obesity was 17% in boys and 12.5% in girls. The prevalence of underweight in girls was 5.8%; while in boys it was 4.5%. The total prevalence rate of underweight according to the national criteria was 5.2%. However, this rate increased to 12% and 12.6% by using WHO and CDC cut-off points, respectively. The highest prevalence of overweight was obtained by CDC (15.8%), followed by WHO (13%); while national cut-off points resulted in 9.7%. Furthermore, 9.2% of the studied population was found to be obese by WHO; while this rate was 4.2%, and 5% by CDC and national cut-off points. Conclusion: This study indicated the coexisting prevalence of underweight and obesity and high prevalence of overweight among children and adolescents in Lorestan province. Furthermore, using the WHO and CDC criteria leads to overestimating the prevalence of weight disorder compared to the national cut-off points in Iran.

The sclera is considered as the principal load-bearing tissue within the eye. The sclera is negatively charged; thus, it exhibits mechanical response to electrical stimulation. We recently demonstrated the electroactive behavior of sclera by performing experimental measurements that captured the deformation of the tip of scleral strips subjected to electric voltage. We also numerically analyzed the electromechanical response of the tissue using a chemo-electro-mechanical model. In the pre-sent study, we extended our previous work by experimentally characterizing the deformation profile of scleral strips along their length under electrical stimulation. In addition, we improved our previous mathematical model such that it could numerically capture the large deformation of samples. For this purpose, we considered the transient variability of the fixed charge density and the coupling between mechanical and chemo-electrical phenomena. These improvements in-creased the accuracy of the computational model, resulting in a better numerical representation of experimentally measured bending angles.
