Objective

To analyze the association between the dietary protein/energy ratio and percentages of dietary animal and plant protein and obesity in Japanese patients with type 2 diabetes.

Design

This was a cross-sectional study. Obesity was defined as BMI ≥25 kg/m². Data were collected for all study participants and stratified according to age and sex. Diet was assessed via a food frequency questionnaire.

Setting

26 clinics participating in the Japan Diabetes Clinical Data Management Study Group (JDDM) from December 2014 to December 2019.

Participants

1567 Japanese out patients with type 2 diabetes (63.1% men; mean age 62.3 ± 11.6 years).

Results

In all participants, multivariate analysis with adjustment by major confounders showed a significant inverse association in those in the highest quartile of the protein/energy ratio (mean 17.7%) with obesity (OR = 0.588, 95% CI = 0.435-0.794; p trend = 00.007), but after the addition of vegetable intake it became non-significant. In the age- and sex-stratified analysis, a high protein/energy ratio (mean 15.6%) was inversely associated with obesity in older women only (OR = 0.280, 95% CI = 0.123-0.638), which remained significant after adjustment of individual food groups correlated with protein. No association between percentages of dietary animal or plant protein and obesity was found.

Conclusions

In older women only, a higher dietary protein/energy ratio was associated with lower obesity after adjustment by confounders and individual food groups correlated with protein intake. Future longitudinal research that includes data on food groups as well as age- and sex-stratification of participants is recommended to further clarify this relationship.

A high prevalence of vitamin D deficiency has been reported in Malaysian pregnant women, indicating that neonates at birth are at increased risk of vitamin D deficiency. Factors including low dietary vitamin D intake and single nucleotide polymorphisms in the vitamin D metabolism genes have been associated with this deficiency in the population. However, there was limited data available regarding the prevalence of neonatal vitamin D deficiency and the factors associated with it among neonates in Malaysia. Therefore, this study aimed to determine the prevalence of vitamin D deficiency and explore the associations between maternal and neonatal gene polymorphisms, as well as non-genetic factors and neonatal vitamin D deficiency. A total of 217 mother-neonate dyads were recruited for this study. Data on skin type, maternal sun exposure, dietary intake, as well as maternal and neonatal 25-hydroxyvitamin D (25OHD) concentrations were collected. Maternal and neonatal vitamin D Receptor (VDR) SNP (rs2228570) and Group-specific component (GC) SNPs (rs4588 and rs7041) genotypes were determined using high-resolution melting (HRM) and restriction fragment length polymorphism, respectively. The results showed that 60.4%, 71.4% and 95.4% of neonates had cord blood 25OHD levels below 25 nmol/L, 30 nmol/L and 50 nmol/L, respectively. After adjusting for the maternal vitamin D status, the maternal VDR rs2228570 GG genotype was significantly associated with neonatal vitamin D deficiency (25OHD<30 nmol/L) (aOR = 2.63, 95% CI: 1.18–5.87, p = 0.018). Maternal vitamin D supplement intake was found to be a protective factor. However, maternal and neonatal vitamin D binding protein (VDBP) SNPs were not associated with neonatal vitamin D deficiency. The high prevalence of neonatal vitamin D deficiency reported in this study indicates the urgent need for the development and implementation of strategies to improve neonatal vitamin D status. The findings suggest that maternal supplementation may be an effective approach to enhance the vitamin D status of neonates.

Background & aims

Habitual dietary pattern has been shown to be a major modulator of systemic inflammation and is considered a modifiable risk factor for cardio-metabolic diseases (CMDs) and mental health disorders. We examined whether dietary-inflammation is associated with the multimorbidity of CMDs and mental health disorders in urbanizing-villages in southern India. We hypothesized that the participants with higher dietary-inflammation would have a higher burden of multimorbidity.

Materials & methods

We conducted a cross-sectional analysis of 5984 adults (53% male) participating in the Andhra Pradesh Children and Parents' Study. We assessed dietary-inflammation using dietary inflammatory index (DII®) based on intake of 27 micro- and macro-nutrients which were measured using a validated food-frequency-questionnaires. The CMDs and mental health disorders were assessed using standardized clinical procedures and validated questionnaires. ‘Multimorbidity’ was defined as a co-existence of one or more CMDs (hypertension, diabetes, myocardial infarction, heart failure, angina and stroke) and one or more mental health disorders (depression and anxiety). The association of multimorbidity with dietary-inflammation was examined using robust Poisson regression.

Results

The prevalence of multimorbidity was 3.5% and ∼75% of participants were consuming a pro-inflammatory diet (DII >0.0). As compared to the 1st DII-quartile (least dietary-inflammatory group), the adjusted prevalence ratio (95% confidence interval) for the presence of multimorbidity was 1.46(0.87, 2.46) for 2nd, 1.75(1.05, 2.89) for 3rd, and 1.77(1.06, 2.96) for 4th DII-quartile (p-trend = 0.021). There was no evidence of an interaction between DII and sex on multimorbidity.

Conclusions

Dietary-inflammation had a positive linear association with the multimorbidity, which suggest that even modest reduction in dietary-inflammation may reduce the multimorbidity burden.

The study aimed to evaluate the effectiveness of a culinary nutrition education program at a 3-month follow-up, in terms of children's dietary practices and variety. The randomized-controlled trial was conducted among Malaysian children aged 10–11 years, in a school-based setting. The main intervention components include a parent-child session on the home food environment, followed by 5 experiential healthy meal preparation sessions, conducted fortnightly with each session lasting an hour. Dietary data were collected using an adapted guided form, in line with the Malaysian Dietary Guidelines for Children and Adolescents at baseline, post-intervention, and a 3-month follow-up (intervention: n = 41, control: n = 42, drop-out rate: 15.3 %). Overall, the children recruited were mainly from low-to middle-income households (76 %) whose families attained at least secondary or tertiary education (95 %). At the 3-month follow-up, significant group and time interaction effect (p < 0.001) revealed that the intervention group consumed whole grains (F-stat = 24.04), fruits (F-stat = 30.45), and vegetables (F-stat = 77.69) more frequently, while the frequency consumption of the control group remained relatively stable over time. Similarly, desirable change was seen favoring the intervention group (p < 0.001) for refined grains (F-stat = 30.96), processed foods (F-stat = 49.74), and sweetened beverages consumption (F-stat = 40.78). Further, the intervention group had good diet variety during dinnertime, compared to the controls (χ² = 5.655, p = 0.017). Findings highlighted the prospect of experiential culinary nutrition programs in advocating healthy eating behavior among children.

Short chain fatty acids (SCFA) have been linked to women's reproductive health, though to a lesser extent, alteration in the production of SCFA and SCFA-producing bacteria has been associated significantly with pregnancy-related complications, unfavourable pregnancy outcomes, menstrual anomalies, and gynaecological cancer.

The female reproductive system is a delicate, intricate, hormone-dependent group of tissues required for the continuity of life and the species' survival. Reproductive health impacts the ovarian function to implantation and foetal development. Several environmental and physiological factors contribute to mammalian infertility concerns caused by a change in reproductive health status. Several lifestyle factors have been demonstrated to affect reproductive health, including age, body weight, smoking, alcohol consumption, work stress, exercise, diet, and nutrition. Nutrition influences puberty, the menstrual cycle, ovulation, conception, implantation and early foetal development. This review provides an overview of how intestinal derived SCFAs maintains female reproductive health summarizing the current knowledge and future perspectives. Microbial SCFAs improve human metabolism by interfering with, glucose homeostasis, appetite regulation and lipid metabolism. Also affect host immunity and intestinal barrier integrity via primary by inhibition of Histone deacetylases (HDAC) mechanism. Therefore, SCFAs exhibit anti-inflammatory, anti-obesity, immunoregulatory, anti-diabetes, anti-cancer, hepatoprotective, cardiovascular protective and neuroprotective properties.

This review highlights recent findings on SCFA and gynaecological pathologies such as preeclampsia, gestational diabetes, pregnancy complications, polycystic ovary syndrome, bacterial vaginosis, and endometriosis to describe current knowledge of the relationship between SCFA and reproductive health and disease in women.

Objective

This study aimed to assess the data of a healthy population at the Korean national level to explore the prevalence of dietary supplement (DS) use changes and the contribution of DSs to micronutrient intake during the pandemic.

Research methods and procedures

Data from the first (2019, before the COVID-19 pandemic) and second (2020, the year that the acute pandemic caused substantial life changes) years of the eighth Korea National Health and Nutrition Examination Survey (KNHANES) were investigated using a weighted complex sample design. Conversions (supplementation/dietary intake (S/D ratio), supplementation to total intake (StT), and supplementation to reference (StR)) were presented to investigate DS dependency and demonstrate that individuals’ nutrient intake derived from DSs increased.

Results

The total adult population was 4871 and 4421 in 2019 and 2020, respectively. Among healthy adults, 64.2% took DSs in 2020, 7.2% higher than that in 2019 (P < 0.001). Among those aged 30–49 years, 70.2% used DSs in 2020, a 9.1% increase from 2019 (P = 0.015). The S/D ratio of vitamin C intake was 6.45 ± 0.95 in 2020, which was greater than that in 2019 (3.82 ± 0.47, P = 0.038). The StT of Ca intake was 7.79 ± 0.98% in 2020, which was greater than that in 2019 (4.89 ± 0.60%, P = 0.020). The StR of vitamin B₁ intake was greater in 2020 (505.01 ± 36.95%) than in 2019 (368.82 ± 29.55%, P = 0.004).

Conclusion

DS dependency greatly increased during the COVID-19 pandemic and was accompanied by increased DS consumption and decreased Ca, vitamin B₁, and vitamin C intake in the healthy Korean population.

Background and aims

Until COVID-19, obesity was the main pandemic of 21 century. To date, there have been 767984989 confirmed cases, and 6943390 include death cases of COVID-19 (WHO). To find the prevalence of Obesity among adults, to adjudge the attitude and behavior of selected subjects towards eating healthy and weight loss during pre- and post-COVID-19.

Methodology

Subject selection was done through non-probability judgemental sampling. Initially, 70 young adults between 18 and 39 years of age were selected from different localities of Delhi (NCR). The study was conducted based on a questionnaire developed for the survey. Based on the inclusion criteria only 50 subjects were selected for further study. The study was constructed into three phases and the arrangement of subjects was elaborated as under. Phase 1 includes field study, clinical examination, and biochemical analysis, phase II includes the division of experimental and control groups, whereas Phase III includes the pre& post-COVID nutritional status, anthropometric assessment, beverage consumption, and sleep patterns were also assessed.

Result

The nutrition intervention in E3 (balanced diet + nutrient supplement) showed a significant difference with the control group followed by E2 (nutrient supplement) and E1 (balanced diet). Our findings showed that the subjects have Calorie, protein, fat, carbohydrates, sodium, and potassium intake significantly decreased (P= <0.001) during post-intervention, whereas, the fiber, vitamin A, vitamin C, and iron (P= <0.001), and calcium (p = 0.006), intake significantly increased during post-intervention. The changes in anthropometric parameters such as waist-to-hip ratio (WHR), body mass index (BMI), and fat% for pre-COVID-19 were higher for both men and women, but after following the dietary recommendation and physical activity found a significant reduction in WHR, BMI, and fat% (P= <0.001) for both men and women. The p-value for subjective sleep quality, sleep latency, habitual sleep efficiency, sleep disturbances, and daytime dysfunction appears to be less than 0.05 which shows that it is significant. The daily consumption of various beverages listed above with a comparison of pre-post intervention, which shows that only for kada the p-value is 0.001 which is less than 0.05 hence it seems significant. The p-value for people with no comorbidity appears less than 0.05, indicating it is significant. majority of participants (12 %) with diabetes took comparatively longer than the participants suffering from other comorbidities followed by Hypertension (7 %), Hyperthyroidism (4 %), Hypothyroidism, and polycystic ovarian disease (PCOD) (3 % each) respectively.

Conclusion

In the present study, we provided survey data about the key aspects of the nutritional management of COVID-19 (pre-and-post), based on the current knowledge.

Objectives

This study aimed to assess the nutritional status and dietary fatty acid intake among children from low-income households in Sabah, Malaysia.

Methods

This cross-sectional study was conducted from December 2022 to February 2023 in Kota Kinabalu and Tawau. A total of 182 children aged 5–12 years from low-income households (less than RM 4850 per month) were recruited. Anthropometric measurements included body weight, height, and body mass index. Dietary intakes were assessed using a 24-h diet recall and the fatty acid (FA) intakes were analyzed using a database with FA content for local foods.

Results

The mean age of children was 8.8 ± 1.8 years, with a majority being girls (53.8%) and of Bajau ethnicity (53.3%). Based on the anthropometric measurements, 16.5% of children were stunted, 7.1% were thin, and 21.4% were overweight or obese. Intakes of total fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), and trans fatty acids as a percentage of total energy were 29.3%, 12.3%, 12.6%, 4.0%, and 0.05%, respectively. 77.5% of children exceeded the recommendation for SFA and 63.2% of children did not meet the recommendation for n-3 PUFA. All children did not meet the recommendation for ⍺-linolenic. Children from Tawau had greater consumption of n-3 PUFA (p < 0.001) while children from Kota Kinabalu had greater intakes of total fat (p = 0.020), MUFA (p = 0.005), n-6 PUFA (p = 0.015), and trans fatty acid (p = 0.001). None of the dietary fatty acids was associated with anthropometric indices.

Conclusions

There was a high prevalence of stunting and overweight or obesity among children from low-income households in Sabah. Most of the children failed to meet the recommendations for SFA and n-3 PUFAs. These findings indicate a compelling need for the implementation of nutritional strategies to enhance adherence to dietary recommendations for fatty acids.

The rapid and extensive transmission of the SARS-CoV-2 virus has led to a worldwide COVID-19 pandemic. Initially thought to be an acute illness, many patients have reported persistent and recurring symptoms even after the infectious period. This has given rise to a new epidemic known as "long-COVID" or post-acute sequelae of coronavirus disease, which has significantly impacted the lives of millions of individuals globally. The symptoms of both COVID-19 vary from person to person, but they share similarities with other respiratory viruses, such as chest pain, shortness of breath, and fatigue, as well as adverse effects on metabolic and pulmonary health. Nutrition plays a crucial role in immune function and metabolic health, and therefore, it is believed to have an impact on reducing the risk or severity of symptoms for both COVID-19. However, despite the importance of nutrition in these physiological functions related to COVID-19, the exact role of nutrition in the onset or severity of COVID-19 infection is still not fully understood. This review aims to explore established and emerging nutrition approaches that may have a role in COVID-19, while emphasizing the significance of established nutrition and clinical practice guidelines as the primary resources for patients and healthcare practitioners.

Background

COVID-19 adversely affects the nutritional characteristics of patients which may negatively impact their quality of life (QOL). The current study determined the association between the nutritional status of COVID-19 patients, its impact on their QOL, and the factors that affected patients' QOL.

Methods

A cross-sectional study was conducted at Al Madinah Al Munawarah in Saudi Arabia. Patients confirmed with COVID-19 infection by a nucleic acid-positive test and identified as acute severe or acute non-severely ill were enrolled. The World Health Organization Quality of Life Questionnaire (WHO-BREF QOL) was used to assess the patients' QOL, and nutritional status was assessed using the Malnutrition Screening Tool. Demographic characteristics, food intake, and body mass index (BMI) were also assessed. Data was analyzed using SPSS version 28.

Results

515 patients were enrolled, with 391 (76%) having acute non-severe symptoms. Patients (15%) were malnourished and suffered from loss of appetite (32%), low food intake (19.4%) and weight loss (16%). Most patients were satisfied or very satisfied with their health (80.2%), and 76.2% rated their QOL as good or very good. Loss of appetite negatively impacted the physical (p = 0.004, 95% CI 0.086, 0.458) and psychological (p = 0.021, 95% CI 0.034, 0.405) QOL domains. Also, decreased food intake affected patients' physical (p = 0.034, 95% CI 0.018, 0.458) QOL domain. Greater weight loss influenced the psychological (p = 0.005.95% CI 0.002, 0.049) QOL domain.

Conclusions

Poor nutritional status among COVID-19 patients was associated with adverse health outcomes and impaired QOL. Nutritional interventions should focus on patients with poor nutritional status or nutrition-related parameters such as weight loss, and loss of appetite which will help improve their QOL.
