Introduction: Online food shopping has a profound impact on people's food acquisition behavior, the current study aims to understand how online food shopping may affect the accessibility of the local food environment and further influence the health equity among different populations.

Methods: Taking 8512 traditional and online greengrocers in central Shanghai as an example, this paper uses Gini coefficient, location quotient and spatial clustering method to compare the equality and equity of food environment between physical and digital food outlets.

Results: It finds that spatial equality is more significantly improved as a result of online food stores than are population equality and social equity of the food environment; older populations are not disadvantaged in terms of healthy food access but lower-income people are; the impact of online stores varies for different regions and different types of stores; depot-based stores have the most positive impact on health equity.

Discussion: Policy implications are discussed to promote the environmental justice of healthy food accessibility.

Background: Although body composition (BC) has been associated with Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), there is little evidence of differences in BC in patients with MASLD regarding body mass index (BMI). The aim of this study was to determine differences in BC in terms of BMI and metabolic comorbidities in patients with MASLD.

Materials and methods: It is a cross-sectional study with patients who attended the check-up unit. Liver steatosis was evaluated by controlled attenuation parameter, and patients were classified into five groups according to BMI, presence of MASLD, and metabolic characteristics: <25 kg/m² non-MASLD; <25 kg/m²-MASLD; Overweight-MASLD; Metabolically Healthy Obese (MHO)-MASLD; and Metabolically Unhealthy Obese (MUO)-MASLD. BC was assessed by bioelectrical impedance and a Bioimpedance Vectorial Analysis (BIVA) was carried out. Differences in BC were analyzed by a One-Way ANOVA test. Univariate and multivariate analyses were performed for factors associated with abnormal BC.

Results: A total of 316 patients were included. 59% (n = 189) were male, with a mean age of 49 ± 10 years. Fat% significantly higher according to BMI was not different between BMI <25 kg/m²-MASLD and Overweight-MASLD groups. Skeletal muscle mass (SMM) was significantly lower in obesity groups with respect to overweight and normal weight groups (p < 0.05); however, no differences were observed in the post-hoc analysis. Extracellular Water/Intracellular Water ratio was significantly higher in the MHO-MASLD group and MUO-MASLD group compared with the BMI <25 kg/m² non-MASLD group and with the BMI <25 kg/m²-MASLD group. Abnormal Waist Circumference (WC) and liver steatosis were independent factors associated with abnormal BC.

Conclusion: BC in MASLD patients varies according to BMI increase; changes could be explained by loss of SMM and not necessarily by the presence of metabolic abnormalities. High WC and the presence of steatosis are independent factors associated with altered BC.

Background: The relationship between dietary antioxidants and fatty liver disease remains a topic of debate. This study aimed to examine the association between the Composite Dietary Antioxidant Index (CDAI) and nonalcoholic fatty liver disease (NAFLD)/metabolic-associated fatty liver disease (MAFLD).

Methods: The study analyzed data from the 2003-2018 cycles of the National Health and Nutrition Examination Survey. The study included 16,321 individuals aged 20-85 years. Food and nutrient intake data were based on the 24-h recall method. Multivariate logistic regression models were employed to examine the relationship between CDAI and NAFLD/MAFLD.

Results: In the fully adjusted multivariate logistic regression model, CDAI demonstrated a significant negative correlation with NAFLD and MAFLD. Mediation analysis showed that inflammatory factors partially mediated the relationship between CDAI and NAFLD/MAFLD prevalence. The combination of high CDAI levels with effective physical activity was associated with a greater reduction in NAFLD/MAFLD prevalence than high CDAI levels alone.

Conclusion: Our study highlighted a negative association between CDAI and NAFLD/MAFLD, mediated by inflammatory factors. Additionally, participants with characteristics of active physical activity and high levels of CDAI were more strongly correlated with the reduced prevalence of NAFLD/MAFLD. Further research in clinical cohorts should be conducted to comprehensively investigate the impact of CDAI on NAFLD/MAFLD prevalence.

Background: Early recovery is a performance indicator of quality care for children under five admitted due to severe acute malnutrition (SAM) at therapeutic feeding centers. Despite the available interventions to tackle such nutritional problems, there is limited information on the time to recovery and its predictors among children with severe acute malnutrition in Ethiopia, more particularly in the study setting.

Objective: The study aimed to assess the time to recovery from severe acute malnutrition and its predictors among children aged 6-59 months admitted to the therapeutic feeding center (TFC) of Hiwot Fana Comprehensive Specialized Hospital (HFCSH), eastern Ethiopia, from 1st September 2019 to 1st March 012024.

Methods: A retrospective cohort study was conducted at the therapeutic feeding center of HFCSH among a randomly selected sample of 349 patients with severe acute malnutrition who were undergoing therapeutic feeding. Data were collected using a data abstraction tool and then stored in Epi-data version 4.6 and STATA version 17.0 statistical software. Descriptive statistics, Kaplan-Meier (KM) plots, median survival times, the log-rank test, and the Cox proportional hazards regression model were used to report the findings of this study. After performing the Cox proportional hazards regression, the model goodness of fit and assumptions were checked. Finally, the association between independent variables and the time to recovery in days was assessed using the multivariable Cox proportional hazards model, and the variables with a p-value <0.05 were considered statistically significant.

Results: The median survival time to recovery among the patients with severe acute malnutrition was 17 days [95% confidence interval (CI): 16-18]. The incidence density recovery rate was 5.7 (95%CI, 4.9-6.6) per 100 person-days of observation. Factors that affected the time to recovery included residing in rural areas [adjusted hazard ratio (AHR) = 2.072; 95%CI = 1.336-3.215], being vaccinated according to age (AHR = 1.848; 95%CI = 1.162-2.939), and lack of analgesic administration (AHR = 0.685; 95%CI = 0.472-0.995).

Conclusion: The median survival time to recovery in this study was found to be optimal. Residency, vaccination status of the child, and analgesic administration were the determinant factors. Paying attention to vaccination coverage, fever management, and pain management as part of the protocol helps reduce the length of hospital stay by facilitating recovery rates among severely malnourished children under five in Ethiopia.

Objectives: Vitamin A plays an important role in health, especially regarding its impact on bone tissue. Vitamin A can lead to bone damage and deformity, thus becoming an important causative factor in osteoarthritis. In this study, we aimed to evaluate the association of serum vitamin A with osteoarthritis.

Methods: We included participants who self-reported whether they had OA in NHANES 2001-2006 and NHANES 2017-2018 to explore the association and dose-response relationship between vitamin A concentration and risk of osteoarthritis through weighted multivariate logistic models and restricted cubic splines. Sensitivity and stratification analyses were also used to assess the robustness of the results.

Results: A total of 18,034 participants were included in this study, and a linear association between serum vitamin A concentration and osteoarthritis risk was observed. The OR of osteoarthritis was 1.22 (95% CI: 0.98, 1.52), 1.40 (95% CI: 1.05,1.85), and 1.47 (95% CI: 1.14, 1.91) for participants in the second, third, and fourth quartiles, respectively, compared with the lowest vitamin A reference group. Similar results were obtained when sensitivity and stratification analyses were performed.

Conclusion: Serum vitamin A is positively associated with osteoarthritis risk. Within a certain range of vitamin A concentrations, vitamin A is a protective factor against osteoarthritis, beyond which it becomes a causative factor for osteoarthritis.

Constipation, a prevalent gastrointestinal disorder, significantly impacts quality of life. This study aimed to investigate the prevalence, risk factors, and implications of constipation in Urumqi City. A cross-sectional survey was conducted from July to August 2023, involving 1,386 participants aged 20-80 years. Data were collected via a self-administered questionnaire, with constipation severity assessed using the Patient Assessment of Constipation Symptoms (PAC-SYM) scale. Key findings indicated that various factors, including residing in rural areas, outdoor work, and sleep disorders, were positively correlated with higher PAC-SYM scores. Conversely, higher daily water intake and certain dietary patterns showed negative correlations. Additionally, increased constipation severity was associated with greater physiological strain and psychosocial concerns (all p < 0.05), emphasizing the disorder's profound effect on quality of life. These findings underscore the need for comprehensive management strategies in Urumqi, considering its diverse lifestyle and dietary factors.

Purpose: Early age of menopause may increase the risk of fracture, cardiovascular diseases, and all-cause mortality. This study aimed to investigate the relation between early-life undernutrition in the Great Chinese Famine and the risk of early natural menopause.

Methods: A famine exposure retrospective cohort was established during 2017-2018. Postmenopausal women who were born on 01 October 1956-30 September 1964 and came to the hospital for routine health examinations were candidates for the study. Famine time was defined from 1 January 1959 to 31 December 1961. Three types of early-life famine exposure status were determined by the participant's date of birth. Natural menopause age below 45 was defined as early menopause. The association between early-life famine exposure status and the risk of early natural menopause was confirmed by multiple logistic regression.

Result: A total of 3,337 participants born around famine were included in this study. The prevalence of early menopause was 13.1, 10.0, and 8.3% for those born before, during, and after the famine, respectively. The multiple logistic regression showed that women born before famine significantly increased the risk of early menopause compared to non-exposure (born after famine) (the fully adjusted OR = 1.463, 95%CI = 1.049-2.042). The fetal famine exposure did not significantly increase the risk of early menopause (the fully adjusted OR = 1.244, 95%CI = 0.878-1.764).

Conclusion: Long-term early childhood famine exposure, which caused chronic undernutrition at young ages, increased the risk of early menopause. Early lifetime undernutrition can be recognized as an adverse factor in female reproductive development and aging. This cohort study further confirmed the hypothesis of developmental origins of health and disease from the aspect of women's reproductive health. Further mechanism study is warranted.

Background: Implementing appropriate complementary food hygiene practices is essential to lower the incidence of food-borne disease and malnutrition in children. However, this aspect is often overlooked in resource-limited settings, and information regarding these practices is not fully available and is not assessed enough. Therefore, this study aimed to assess complementary food hygiene practices and their associated factors in Dessie Zuria, South Wollo Zone, Amhara, Ethiopia, in 2023.

Methods: An institutional-based cross-sectional study design was conducted from 17 April to 18 May 2023, among 366 mothers with children aged 6-23 months. Dessie Zuria was purposively selected, and a systematic random sampling technique was used to recruit study participants. Data were collected using pretested and structured questionnaires. Finally, the data were entered using EPI-info and then exported to SPSS version 26. Bivariable and multivariable logistic regression analyses were used to identify factors associated with complementary feeding hygiene practices. Both crude odds ratios (COR) and adjusted odds ratios (AOR) with a 95% confidence level (CI) were computed, and a p-value of <0.05, in the final model, was considered statistically significant.

Results: The proportion of households practicing complementary food hygiene was 22.22%. Factors associated with these practices included access to media such as television or radio (AOR = 10.51, 95% CI: 2.8, 39.28), starting complementary feeding before 6 months (AOR = 2.01, 95% CI: 1.05, 3.84), and the child's age being 6 to 11 months (AOR = 0.25, 95% CI: 0.08, 0.7).

Conclusion: The prevalence of complementary food hygiene practices was poor. Healthcare professionals should promote starting breastfeeding at the age of 6 months. In addition, media companies ought to make an effort to create a positive social and cultural environment that encourages complementary feeding practices for young children.
