Factors associated with hypoalbuminemia and malnutrition risk in older inpatients: A detailed analysis of demographic and clinical characteristics Tran Thi Phuong Lan, , Pham Van Phu, Le Thi Huong, Le Xuan Hung, Nguyen Quang Dung, , and Aims Public Health, 2025 Malnutrition and hypoalbuminemia are critical health challenges among hospitalized older adults, contributing to increased morbidity, prolonged hospital stays, and higher mortality risks. In this cross-sectional study, we aimed to determine the prevalence and factors associated with hypoalbuminemia and malnutrition risk in older inpatients at Military Hospital 354, Hanoi, Vietnam, from January–June 2025. A total of 264 patients aged 65 and older were recruited from geriatric, internal medicine, and rehabilitation wards. Hypoalbuminemia was defined as serum albumin levels <35 g/L, and malnutrition risk was assessed using the Mini Nutritional Assessment-Short Form (MNA-SF; score < 12). Data on demographic (age, sex, education, cohabitation) and clinical/biochemical factors (primary diagnosis, hemoglobin, lymphocyte, zinc, ferritin) were collected within 48 hours of admission. The prevalence of hypoalbuminemia was 33.0%, and 73.5% of patients were malnourished or at risk of malnutrition. Multivariable logistic regression identified older age (AOR 1.09, 95% CI 1.01–1.18) and male sex (AOR 2.17, 95% CI 1.14–4.17) as significant factors associated with malnutrition risk, while female sex was protective for both hypoalbuminemia (AOR 0.48, 95% CI 0.27–0.86) and malnutrition risk (AOR 0.46, 95% CI 0.24–0.88). Higher lymphocyte counts were associated with hypoalbuminemia (AOR 1.24, 95% CI 1.00–1.53). Spearman's correlations revealed strong positive associations between zinc and ferritin (r = 0.74, p < 0.01) and negative correlations of age with zinc (r = −0.43) and ferritin (r = −0.33). These findings highlight the high burden of nutritional deficits in Vietnam's older inpatients and underscore the need for routine MNA-SF and albumin screening to guide early interventions, particularly targeting micronutrient deficiencies in resource-constrained settings.
Fruit and vegetable intake and stomach cancer among male adults: A case-control study in Northern Viet Nam Le Hong Phuoc, Khanpaseuth Sengngam, Toshio Ogawa, Nlandu Roger Ngatu, Shunya Ikeda, Tran Hieu Hoc, Pham Van Phu, Dinh Thi Minh, Le Tran Ngoan Asian Pacific Journal of Cancer Prevention, 2020 OBJECTIVE: This study investigated the association between fruit and vegetable intake and stomach cancer, with considering the impacts of Helicobacter pylori (H. pylori) infection and tobacco smoking. METHODS: A case-control study featuring 80 male incident stomach-cancer cases and 146 male controls was conducted in a general hospital in Viet Nam. A semi-quantitative food frequency and demographic lifestyle questionnaire were used; and venous blood samples were collected to determine H. pylori status by IgG ELISA. The respective associations between fruit and vegetable intake and stomach cancer were examined using unconditional logistic regression analysis with adjustments for possible cofactors. RESULTS: Fruit intake and stomach cancer showed a weak inverse association when this became non-significant after adjusting for H. pylori infection (OR = 0.50, 95%CI: 0.22-1.12, p trend = 0.094). Stratifying by H. pylori status returned a negative trend for fruit intake and stomach cancer among H. pylori-negative participants (OR = 0.21, 95%CI: 0.06-0.69, p trend = 0.010), but no significant interaction for H. pylori-positive participants (OR = 0.76, 95%CI: 0.21-2.68, p trend = 0.670). Vegetable intake and stomach cancer showed no association, regardless of H. pylori status. Compared to ever-smokers with low intake, never-smokers with high vegetable (OR = 0.25, 95% CI: 0.06-0.95) and fruit intake (OR = 0.20, 95%CI: 0.06-0.65) showed the lowest odds of stomach cancer. CONCLUSIONS: Fruit, but not vegetable, intake showed a weak inverse association with stomach cancer. H. pylori infection and tobacco-smoking status may influence the protective effects of fruit and vegetable intake on stomach cancer.<br />.
Childhood overweight and obesity amongst primary school children in Hai Phong City, Vietnam Thị Đức Ngàn Hoàng, Lê Danh Tuyên, Pham Van Phu, Smita Nambiar Asia Pacific Journal of Clinical Nutrition, 2018 BACKGROUND AND OBJECTIVES: Childhood obesity is a rising health concern in Vietnam, however, research in this area is not extensive. The aim of this study was to determine the prevalence of childhood overweight and obesity, and to study associations between weight status and selected lifestyle factors, such as diet and physical activity levels, among children aged 6-10 years in Hai Phong City, Vietnam. METHODS AND STUDY DESIGN: Two hundred and seventy-six children from an urban and a rural primary school participated in this cross-sectional study. Data on weight, height and waist circumference were used to calculate BMI, and waist-height ratio to determine the proportion of children who were overweight, obese and had high central adiposity. Information on diet, physical activity and socioeconomic status of families was collected using questionnaires. RESULTS: Prevalences of overweight, obesity and high abdominal adiposity were 11.2%, 10.1% and 19.9%, respectively. Children who completed >=60 minutes of physical activity daily were 50% and 80% less likely to be overweight and have high abdominal adiposity, respectively. Computer usage increased the odds of overweight and high abdominal adiposity by 4.5 and 3.9 times, respectively. Mothers with higher education and income levels increased the risk of their children being overweight (p<0.05). CONCLUSIONS: Physical inactivity and high maternal education and income levels increased the risk of childhood overweight and obesity in this cohort. Future interventions should target parents and their children by providing both with educational modules centred on healthy eating habits, parental feeding practices and strategies for increasing physical activity.
