Summary: This study evaluated the validity and reproducibility of a semiquantitative food frequency questionnaire (SFFQ) in adult populations in China. The SFFQ was found to provide valid estimates for most food groups and performed well in estimating habitual intakes of unsaturated fatty acids. However, the overall correlation between the SFFQ and the 24-hour dietary records was relatively low. The reproducibility of the SFFQ was moderate for food group estimates.

Summary: This study examined the validity and reliability of an FFQ designed to estimate dietary vitamin D and Calcium intakes in Iranian childbearing age women. The results indicated that the FFQ has acceptable validity for estimating vitamin D and Ca, with stronger reliability for Ca than for vitamin D.

Summary: The study found that the interviewer-administered food frequency questionnaire in The Malaysian Cohort has good relative validity in assessing participants' dietary habits, but estimates for iron, vitamin A, and vitamin C should be interpreted with caution.

Summary: This study evaluated the validity and reproducibility of qualitative and quantitative food frequency questionnaires (FFQs) in the Chinese population. The results showed that most food items in both the qualitative and quantitative FFQs had acceptable or good validity and reproducibility in the CKB study. However, dried vegetables and carbonated soft drinks performed poorly, indicating the need for modification and validation in future research.

Summary: This study investigated the dietary patterns of pregnant women in urban South Africa and found a prevalence of low-quality diets. Different dietary patterns were associated with factors such as maternal educational level and socioeconomic status. Addressing the low dietary quality among pregnant women in urban South Africa is crucial for optimal maternal and offspring health outcomes.

Summary: This study explored the association between emotional eating and dietary patterns, and found that fat intake was significantly associated with emotional eating, and educational level could be a predictor of emotional eating. The results highlight the importance of emotional eating and the significance of healthy food for a healthy lifestyle.

Summary: Dietary fiber is important for health, and a validated tool for assessing food consumption related to high-fiber foods can help quantify the intake of fiber, identify risk groups and target populations, and inform the development of health policies and programs. In this study, a fiber intake short food frequency questionnaire (FFQ) was translated into Spanish, validated by experts, and tested on 198 Chilean adults. The FFQ showed a high validity coefficient of 0.98 and revealed that the mean dietary fiber intake in Chilean adults was similar to the national survey data.

Summary: Vitamin D is essential for bone health and preventing metabolic bone disorders. Vitamin D deficiency is common in Italy and supplementation with vitamin D2 or D3 is often recommended. However, studies on vitamin D intake in the Italian population are not well-designed and incomplete. This study aimed to validate a food questionnaire for assessing dietary vitamin D intake in Italians and found a low intake of vitamin D, which contributes to hypovitaminosis D.

Summary: This study assessed the use of dietary supplements among cancer survivors and those at increased risk for cancer using a food frequency questionnaire (FFQ) and 24-hour dietary recalls (DRs). The results showed good reproducibility of the FFQ over 1 year and comparable estimates to the more detailed DRs.

Summary: The study found that students living on islands were more likely to be overweight and obese compared to their mainland counterparts, and they also had lower fitness levels. Additionally, island-dwelling students had higher rates of low physical fitness and overweight/obesity. Increased general and abdominal adiposity negatively impacted students' performance in physical fitness tests.

Summary: Lactose intolerance can be caused or worsened by a deficiency of beta-galactosidase in the gastrointestinal tract, leading to symptoms such as diarrhea, abdominal pain, bloating, flatulence, and nausea. Although results were not consistent across studies, lactose-free or low-lactose dairy products are important for the diet of lactose intolerant individuals, providing essential nutrients and reducing the risk of deficiencies.

Summary: Obese patients with HFpEF showed a decreased risk of cardiovascular events when using spironolactone compared to nonobese patients. There was a linear association between BMI and waist circumference with the effect of spironolactone, becoming significant at certain thresholds. Further prospective randomized studies in obese subjects are needed to confirm these findings.

Summary: The study found that approximately 20% of people in the Athens metropolitan area were diagnosed with metabolic syndrome (MetS), with a higher prevalence in men compared to women. Areas with more green urban spaces and sports facilities had lower MetS prevalence, whereas greater density and availability of supermarkets and street markets were associated with lower MetS prevalence. The beneficial role of the built environment's characteristics on MetS prevalence was stronger in the male population, while the preventive effect of the food environment's characteristics was stronger in the female population.

Summary: This study identified four different trajectories of processing speed through aging, with factors such as female sex, higher education level, moderate physical activity, marital status, and higher wealth level associated with higher trajectories. On the other hand, presence of cardiovascular disease, diabetes mellitus, and depressive symptoms were associated with lower processing speed scores across most trajectories. All these factors could be important targets for interventions to reduce age-related cognitive impairment.

Summary: This study aimed to investigate the impact of persisting amblyopia into adulthood and found a decline in overall frequency since the introduction of universal child vision screening in the UK. Most adults treated for amblyopia in childhood still have vision deficits, but there is no evidence of vision-mediated effects on educational, employment-related, or economic outcomes.

Summary: This paper describes the methodology for constructing reference intervals when the response variable is bounded and explores different distribution families for centile estimation. Results indicate that z-scores and extracted centiles improved when kurtosis was modeled and the ceiling effect was addressed with the use of the inflated binomial distribution.

Summary: Leukocyte telomere length (LTL) is considered as a marker of biological age, with older age, male sex, and higher white cell count associated with shorter LTL. Additionally, there are differences in LTL between different ethnicities and sexes. This study provides an opportunity to further investigate the variation in LTL.

Summary: Children's health literacy is crucial for their health, and this study investigated the association between health literacy and weight status among Greek schoolchildren aged 10 to 12 years old. The study found that a higher level of health literacy was associated with lower body mass index in children. Girls had higher health literacy levels than boys, and the majority of students had high health literacy levels.

Summary: The health status of parents partially affects the nutrition literacy level of their children, with paternal BMI status and hypertension being inversely associated, while paternal diabetes and maternal dyslipidemia are positively associated. Parents' adherence to nutritional recommendations plays a crucial role in shaping their children's nutrition literacy.
