Objective This report aimed to compare the total daily energy expenditure (TDEE) of adolescents measured by doubly labeled water (DLW) with the 2005 and 2023 dietary reference intake (DRI) equations proposed by the Institute of Medicine (IOM) in a sample of Brazilian adolescents. Methodology: This is a cross-sectional and observational study with a convenience sample of 15 obese and eutrophic adolescents, aged between 11 and 14 years, from public schools and the obesity outpatient clinic of the Clinics Hospital of the Ribeirão Preto Medical School – University of São Paulo (HC FMRP-USP) in Brazil. Were obtained stature and weight by conventional methods and used to calculate the body mass index (BMI) to determine the nutritional status. Fat-free mass (FFM) was measured using dual-energy X-ray absorptiometry. Energy expenditure was determined by DLW and estimated by the 2005 and 2023 DRI equations. The level of physical activity was measured with the ActivPAL™ accelerometer to classify adolescents within the equations. Results: Forty-seven percent of the sample were eutrophic and 53% were obese. The adolescents were classified as somewhat active according to the average number of daily steps. The DLW-derived TDEE and the TDEE derived from the 2005 and the 2023 predictive equations are presented as means, standard deviations, and 95% confidence intervals (CI). The 2005 and 2023 DRI equations produced significantly higher values than the DLW-determined TDEE (56.2% and 57.2%, respectively). Conclusion: Additional studies with Brazilian adolescents should be conducted to propose more accurate and specific predictive TDEE equations. Show less

This article has been retracted on 30 August 2025. VIEW THE RETRACTION NOTICE (https://doi.org/10.14302/issn.2379-7835.ijn-25-5842) Objective The COVID-19 pandemic has led to the global research efforts to identify the risk factors which would lead to severe COVID-19 disease. This study aimed to investigate the relationship between body mass index (BMI) and severity of coronavirus disease 2019 (COVID-19). Methods A total of 2820 patients hospitalized with COVID-19 disease in nine Government Medical Colleges, COVID hospitals or COVID care centers of Maharashtra were included in the study. Interviews were conducted on the telephone and counselling was done. Results Among 2820, 2442 (86.60%) were asymptomatic or had a mild or moderate illness. More than half of the total COVID- 19 positive cases, 1591 (56.41%), were in the normal BMI range, and of these only 183 (11.50%) had severe COVID-19 disease. On the other hand, 647 (22.94%) patients were overweight and 106 (16.38%) had Severe COVID- 19 disease. Similarly, the patients who were obese, 363 (84.03%) were asymptomatic and 69 (15.97%) had severe COVID- 19 disease. Odds ratio for this association was found as 1.5, which indicates that patients who were obese (BMI ≥ 27.5) had one and half times increased odds of progression to severity as compared to patients having normal BMI. This association was found to be statistically significant (p- value < 0.05). Conclusion Our findings highlight the significant role of BMI in clinical progression of COVID-19 disease. Patients with underweight and obesity experienced more severe outcomes than those of normal weight when being hospitalized with COVID-19 disease. Show less

Iron deficiency is a major public health problem worldwide. It affects a significant proportion of the population, and is responsible for around 50% of anemia cases worldwide. Cameroon in general and Lekie Division in particular, is very highlyaffected by this problem. However, early detection of the problem can prevent the fatalities associated to it. The objective of this study was to provide up-to-date, detailed data on the markers of iron status in these populations, so that treatment can be better targeted. A two-month cross-sectional study was conducted in the Lekie Division in collaboration with local health centres in both urban and rural areas. The study sample consisted of 361 participants of all age groups and sexes. A questionnaire was issued to obtain information of the participants socio-demographic status, then 3 to 5ml of blood were collected and a number of markers of the participants iron status were studied. Of all the hematological markers studied, hemoglobin concentration in the study population was below normal in both men and women. Biochemical markers were good for all socio-demographic parameters. The mean values of biochemical and hematological markers in the population of the Lekie Division were good for all socio-demographic parameters, with the exception of hemoglobin concentration, which remains critical, requiring particular attention in this locality, but above all urgent intervention lest the situation aggravates further.

The benefits of exclusive breastfeeding are well-known. Despite the legislative and systemic efforts to promote breastfeeding in South Korea, the nation’s current rate of exclusive breastfeeding (5.2%) during the infant’s first six months is alarming. Under the framework of the theory of planned behavior (TPB), this study elicited the beliefs around exclusive breastfeeding commonly held by low-income women participating in NutriPlus, the community nutrition program. Using a convenient sampling method, online open-ended surveys were conducted with two program clinics in Seoul during spring of 2024. The survey included questions about their demography and beliefs regarding indirect theoretical constructs of the exclusive breastfeeding behavior by listing top three things that came to their mind. A total of 120 NutriPlus clients participated in this survey. Though 53.1% of postpartum women were breastfeeding, only 28.1% were breastfeeding exclusively. Based on most frequently mentioned beliefs, we classified them to behavioral, normative, and control beliefs under TPB. Modal behavioral beliefs were healthy babies (n=87) and mother-baby bonding (n=71) and feeding issues (n=96) and inconvenience resulting from the act of breastfeeding (n=86). Family members seemed to shape both positive (n=122) and negative (n=37) normative beliefs. The presence of support (n=84) mattered to facilitate breastfeeding, while feeding issues (n=98) played as barriers. Promotion efforts need to emphasize breastfeeding knowledge and skill building and include family members and society at large to improve the awareness and transform barriers of breastfeeding to facilitators.
