RESUMEN

INTRODUCTION: Maternal overweight or obesity has been associated with metabolic syndrome through 1 year postpartum, but it remains unknown whether a culturally-modified, motivationally-targeted, and individually-tailored Lifestyle Intervention could improve postpartum cardiometabolic health among Hispanic women with overweight or obesity. METHODS: Proyecto Mamá was a randomized controlled trial conducted in Western Massachusetts from 2014 to 2020 in which Hispanic women with overweight/obesity were randomized to a Lifestyle Intervention (LI) involving diet and exercise or to a comparison Health and Wellness Intervention (HW). Biomarkers of cardiovascular risk (i.e., lipids, C-reactive protein) and insulin resistance (fasting insulin, glucose, HbA1c, homeostasis model assessment [HOMA-IR], leptin, adiponectin) were measured at baseline (early pregnancy), mid-pregnancy, and 6 weeks, 6 months, and 12 months postpartum. Generalized linear mixed effect models were used to evaluate differences in the change in biomarkers over the course of postpartum follow-up time. RESULTS: In intent-to-treat analyses among eligible women (LI; n=51, HW; n=58) there were no significant differences in changes in biomarkers of CVD risk or insulin resistance over the postpartum year; for example, the intervention effect for total cholesterol was 6.98 (SE: 6.36, p=0.27) and for HbA1c was -0.01 (SE: 0.4, p=0.85). In pooled analyses, regardless of intervention arm, women who participated in any vigorous activity had less of an increase in HbA1c (intervention effect = -0.17, SE: 0.05, p=0.002) compared to those with no vigorous activity, and similarly beneficial associations with other cardiovascular risk biomarkers (p<0.05). DISCUSSION: Women who participated in vigorous activity, regardless of their assigned intervention arm, had more favorable changes in biomarkers of insulin resistance.

RESUMEN

Black African-Caribbean (BAC) populations are at greater risk of cardiometabolic disease than White Europeans (WE), despite exhibiting lower fasting triacylglycerol (TAG) concentrations. However, limited data exist regarding postprandial fatty acid metabolism in BAC populations. This study determined the ethnic differences in postprandial fatty acid metabolism between overweight and obese WE and BAC men. WE [n = 10, age 33.3 ± 1.7 yr; body mass index (BMI) = 26.8 (25.8-31.0) kg/m2] and BAC [n = 9, age 27.9 ± 1.0 yr; BMI = 27.5 (26.0-28.6) kg/m2] men consumed two consecutive (at 0 and 300 min) moderate-to-high-fat meals-the first labeled with [U-13C]palmitate. The plasma concentration and appearance of meal-derived fatty acids in very-low-density lipoprotein (VLDL)-TAG, chylomicron-TAG, and nonesterified fatty acid (NEFA) were determined over an 8-h postprandial period. Indirect calorimetry with 13CO2 enrichment determined total and meal-derived fatty acid oxidation rates, and plasma ß-hydroxybutyrate (3-OHB) concentration was measured to assess ketogenesis. BAC exhibited lower postprandial TAG [area under the curve (AUC0-480) = 671 (563-802) vs. 469 (354-623) mmol/L/min, P = 0.022] and VLDL-TAG [AUC0-480 = 288 ± 30 vs. 145 ± 27 mmol/L/min, P = 0.003] concentrations than WE. The appearance of meal-derived fatty acids in VLDL-TAG was lower in BAC than in WE (AUC0-480 = 133 ± 12 vs. 78 ± 13 mmol/L/min, P = 0.007). Following the second meal, BAC showed a trend for lower chylomicron-TAG concentration [AUC300-480 = 69 (51-93) vs. 43 (28-67) mmol/L/min, P = 0.057]. There were no ethnic differences in the appearance of chylomicron-TAG, cumulative fatty acid oxidation, and the NEFA:3-OHB ratio (P > 0.05). In conclusion, BAC exhibit lower postprandial TAG concentrations compared with WE men, driven by lower VLDL-TAG concentrations and possibly lower chylomicron-TAG in the late postprandial period. These findings suggest that postprandial fatty acid trafficking may be a less important determinant of cardiometabolic risk in BAC than in WE men.NEW & NOTEWORTHY Postprandial TAG is lower in Black African-Caribbean men than in White European men, and this is likely driven by lower meal-derived VLDL-TAG in Black African-Caribbean men. This observation could suggest that fatty acid trafficking may be a less important determinant of cardiometabolic risk in Black Africans than in White European men.

RESUMEN

OBJECTIVE: The objective of this study was to evaluate the efficacy of a mobile health (mHealth)-delivered behavioral intervention on changes in postpartum weight and cardiometabolic risk factors (blood pressure [BP], lipids, and hemoglobin A1c) over 12 months. METHODS: A randomized controlled trial of 300 African American postpartum people with overweight and obesity enrolled in Philadelphia Women, Infants, and Children (WIC) clinics was conducted. Participants were randomized to usual WIC care (n = 151) or a 12-month mHealth-delivered intervention (n = 149) comprising behavior change goals, interactive self-monitoring text messages, and counseling support. RESULTS: Intervention and usual-care participants did not significantly differ in 12-month mean postpartum weight change (1.1 vs. 1.6 kg, p = 0.5; difference -0.6 kg, 95% CI: -2.3 to 1.2). However, high intervention engagement led to weight loss compared with weight gain among those who were less engaged (-0.6 vs. 2.4 kg, p = 0.01; difference -3.0 kg, 95% CI: -5.4 to -0.6). The intervention reduced systolic BP relative to usual care (-1.6 vs. 2.4 mm Hg, p = 0.02; difference -4.0 mm Hg, 95% CI: -7.5 to -0.5), but this effect did not extend to other cardiometabolic risk factors. CONCLUSIONS: Among African American postpartum people enrolled in WIC, an mHealth-delivered intervention reduced systolic BP but not additional cardiometabolic risk factors or weight. Intervention participants with high engagement had significantly better postpartum weight outcomes, and thus, next steps include addressing barriers to engagement.

RESUMEN

Double burden of malnutrition (DBM) is a global public health concern. This study determined the prevalence of DBM and its associated factors among 451 indigenous households in an urbanized state of Malaysia. Mothers and children were measured for weight and height/length. Mothers were interviewed for socio-demographics and diets of mothers and children. Prevalence of DBM (overweight/obese mother and underweight/stunted child) was 28.8%. Food insecurity, maternal height (<150 cm) and energy intake (>recommendation), child's age (≥24 months) and energy intake (

RESUMEN

OBJECTIVE: To understand the nutritional status and physical fitness of the Uygur, Kazak and Han ethnic college students, and to investigate the nonlinear relationship between BMI and physical fitness indexes in different ethnic groups. METHODS: A total of 3 600 Uygur, Kazakh and Han students majoring in non-sports in a university in Xinjiang Uygur Autonomous Region in 2021 were selected by stratified random cluster sampling method. Height, weight, vital capacity, 50 m running, standing long jump, sit-and-reach, sit-up/pull-up and endurance running were measured. Body mass index (BMI), standardized Z score of each test score and physical fitness index (PFI) were calculated. The data were analyzed by Chi-square test, single factor analysis of variance, and nonlinear quadratic regression. RESULTS: Prevalences of overweight (16.00%) and obesity (8.08%) of the Han college students were significantly higher than those of the Uygur (11.83% and 4.08%) and Kazakh (13.58% and 4.58%). Prevalence of low weight in the Uygur (11.92%) was the highest, and the lowest was the Kazakh (9.75%). There were significant differences in the prevalence of BMI classification among the three ethnic groups boys and girls (all P < 0.05). There were significant differences in PFI among college students of different BMI levels in the Uygur, Kazakh and Han ethnic college students (all P < 0.05), and the PFI of normal weight group was higher than the other weight groups in general, and the overweight group was higher than the obese group, but some ethnics showed the highest PFI in the low weight group. The non-linear quadratic regression results showed that the curves of the Uygur boys and girls and the Kazakh boys were inverted "J" shaped, and the PFI increased and then decreased with the increase of BMI, while the rest of the curves were arc-shaped, and the PFI decreased with the increase of BMI. CONCLUSION: Overweight obesity in the Uygur, Kazakh and Han ethnic college students brings about a decrease in physical fitness, but Kazakh low weight male and female and Han low weight grils have better physical fitness than the normal weight groups. Focusing on improving the physical fitness of Uygur low-weight and high-weight boys and Han high-weight girls could effectively reduce the differences in physical fitness of college students in different weight levels and ethnic groups.

RESUMEN

OBJECTIVES: Overweight and obesity (OWOB) starts in childhood, influences adult cardiovascular risk, and is not equally distributed across ethnic groups. It is unclear which effects can be expected from reductions in OWOB across the life course on inequalities in cardio-metabolic diseases in a multi-ethnic population. This study aims to estimate the effects of three scenarios of changes in OWOB (the Normal-Weight-for-All scenario, the No-Ethnic-Difference-over-the-Life-Course scenario, the and No-Ethnic-Differences-in-Childhood scenario). STUDY DESIGN: A simulation study. METHODS: We combine data from multiple data sources and use the Dynamic Modeling for Health Impact Assessment (DYNAMO-HIA) model to estimate the effects of three scenarios on the cumulative incidence of diabetes mellitus, ischaemic heart disease (IHD) and stroke between 18 and 70 years in the five largest ethnic groups in the Netherlands. RESULTS: In the scenario where all individuals have normal weight, the cumulative incidence decreased in all ethnic minority groups for all diseases, with largest decreases among South-Asian Surinamese, where the reduction of diabetes incidence exceeded 50%. In the scenario where the prevalence of OWOB in each ethnic-minority group was reduced to the current level among the Dutch-origin population, ethnic inequalities in cardio-metabolic diseases were substantially reduced, particularly when lowered prevalence of OWOB persisted across the lifespan. Reductions were the largest for diabetes and for the Asian Surinamese population. CONCLUSIONS: A substantial part of the well-known ethnic inequalities in incidence of diabetes, IHD, and stroke can be attributed to OWOB. Interventions aimed at reducing OWOB have clear potential to reduce the health inequalities in these outcomes, especially for diabetes, in particular when they have an impact across the lifespan.

RESUMEN

BACKGROUND: Available data show that the epidemiological profile of most indigenous Brazilian populations is characterized by the coexistence of long-standing health problems (high prevalence of infectious and parasitic diseases, malnutrition, and deficiency diseases, such as anemia in children and women of reproductive age), associated with new health problems, especially those related to obesity (hypertension, type 2 diabetes mellitus and dyslipidemia). Based on this scenario, this study analyzed the nutritional profile of the adult population of seven indigenous peoples from the Brazilian Amazon in the years 2007 and 2021. METHODS: A total of 598 adults individuals were analyzed in 2007 (319 women and 279 men) and 924 in 2021 (483 women and 441 men), from seven indigenous peoples located in the state of Pará, who were assisted during health actions carried out in 2007 and in 2021. Body mass index classification used the World Health Organization criteria for adults: low weight, < 18.5 kg/m2; normal weight, ≥ 18.5 and < 25 kg/m2); overweight, ≥ 25 and < 30 kg/m2, and obesity, ≥ 30 kg/m2. A waist circumference (WC) < 90 cm in men and < 80 cm in women was considered normal. RESULTS: The data revealed heterogeneous anthropometric profiles, with a low prevalence of nutritional changes in the Araweté, Arara and Parakanã peoples, and high proportions of excess weight and abdominal obesity in the Kararaô, Xikrin do Bacajá, Asurini do Xingu and Gavião peoples, similar to or even higher than the national averages. CONCLUSION: Different stages of nutritional transition were identified in the indigenous peoples analyzed, despite apparently having been subjected to the same environmental pressures that shaped their nutritional profile in recent decades, which may indicate different genetic susceptibilities to nutritional changes. The evidence shown in this study strongly suggests the need to investigate in greater depth the genetic and environmental factors associated with the nutritional profile of Brazilian indigenous peoples, with assessment of diet, physical activity and sociodemographic and socioeconomic variables that enable the development of appropriate prevention and monitoring measures.

RESUMEN

The purpose of the study was to conduct in-depth qualitative interviews to understand the lived experiences of African American parents of overweight adolescents who had previously participated in a family-based weight loss program and to utilize these insights to inform the essential elements of the LEADS trial, an integrated resilience stress management and health promotion intervention. Participants (N = 30) were African American parents and/or caregivers (96.7% female; Mage = 49.73, SD = 10.88; MBMI = 37.63, SD = 8.21) of adolescents with overweight and/or obesity. Interviews were transcribed and coded using inductive and deductive approaches for themes by two independent coders. Inter-rater reliability was acceptable (r = 0.70-0.80) and discrepancies were resolved to 100% agreement. Prominent stress themes included caregiver responsibilities, work, interpersonal family conflict, and physical and emotional consequences of chronic stress. Participants also noted decreases in physical activity and poor food choices due to stress. Coping mechanisms included prayer/meditation, church social support, and talking with family/partner. Results highlight the importance of mitigating stress among African American parents through stress management and cultural/familial resilience approaches to increase the likelihood of engagement in behavioral strategies in health promotion programs. Future studies should assess the utility of incorporating stress management components and health promotion techniques to improve health outcomes among African American families.

RESUMEN

Exercise and diet are beneficial for pain, yet many patients do not receive such recommendations from providers. This may be due to biases related to gender, race, and weight. We recruited medical students (N = 90) to view videos of women with chronic back pain performing a functional task; patients varied by weight (overweight/obese) and race (Black/White). For each woman patient, providers rated their likelihood of recommending exercises or dietary changes. Ratings significantly differed across recommendations (F(2.75, 244.72) = 6.19, P < .01) in that providers were more likely to recommend flexibility exercises than aerobic exercises and dietary changes and were more likely to recommend strength exercises than dietary changes. Results also indicated that women with obesity were more likely to receive aerobic (F(1,89) = 17.20, P < .01), strength (F(1,89) = 6.08, P = .02), and dietary recommendations (F(1,89) = 37.56, P < .01) than were women with overweight. Additionally, White women were more likely to receive a recommendation for flexibility exercises (F(1,89) = 4.92, P = .03) than Black women. Collectively, these findings suggest that providers' exercise and dietary recommendations for women with chronic pain are influenced by the weight status and racial identity of the patient. Future studies are needed to identify the reasons underlying these systematic differences, including the stereotypes and attitudes that may be driving these effects. PERSPECTIVE: This article presents results on how patient weight and race impact providers' exercise and diet recommendations for women with chronic back pain. Provider recommendations for these modalities may be systematically biased in a way that impedes care and impacts patient functioning.

RESUMEN

BACKGROUND: Limited research on alanine aminotransferase (ALT) screening for metabolic dysfunction-associated steatotic liver disease (MASLD) among US Asian/Pacific Islander (PI) children necessitates investigation in this heterogeneous population. OBJECTIVE: Examine ALT elevation among Asian/PI children with overweight or obesity. METHODS: Elevated ALT prevalence (clinical threshold) and association with body mass index ≥85th percentile were compared among 18 402 Asian/PI and 25 376 non-Hispanic White (NHW) children aged 9-17 years using logistic regression. RESULTS: ALT elevation was more prevalent among Asian/PI (vs. NHW) males with overweight (4.0% vs. 2.7%), moderate (7.8% vs. 5.3%) and severe obesity (16.6% vs. 11.5%), and females with moderate (5.1% vs. 3.0%) and severe obesity (10.2% vs. 5.2%). Adjusted odds of elevated ALT were 1.6-fold and ~2-fold higher for Asian/PI (vs. NHW) males and females (with obesity), respectively. Filipino, Chinese and Southeast Asian males had 1.7-2.1-fold higher odds, but Native Hawaiian/PI (NHPI) and South Asian males did not significantly differ (vs. NHW). Filipina and Chinese females with obesity had >2-fold higher odds, Southeast and South Asian females did not differ and NHPI findings were mixed (vs. NHW). CONCLUSION: High elevated ALT prevalence among Asian/PI children with overweight and obesity emphasizes the need for MASLD risk assessment and examination of ethnic subgroups.

RESUMEN

Despite well-documented global declines in physical activity (PA) during the COVID-19 pandemic, little is known regarding the specific impact among underserved, rural Alabama counties. This is concerning as this region was already disproportionately burdened by inactivity and related chronic diseases and was among the hardest hit by COVID-19. Thus, the current study examined the effect of COVID-19 on PA in four rural Alabama counties. An ancillary survey was administered between March 2020 and August 2021 to the first cohort (N = 171) of participants enrolled in a larger PA trial. Main outcomes of this survey included the perceived impact of COVID-19 on PA, leisure-time PA, and social cognitive theory (SCT) constructs at 3 months. Almost half of the participants reported being less active during the pandemic (49.7%) and endorsed that COVID-19 made PA more difficult (47.4%), citing concerns such as getting sick from exercising outside of the home (70.4%) and discomfort wearing a face mask while exercising (58%). Perceived COVID-19 impact on PA was significantly associated with education, household dependents, and gender (p's < 0.05). More women, parents, and college graduates reported that the COVID-19 pandemic made PA more difficult. Overall, there were no significant associations between PA, SCT constructs, or perceived COVID-19 impact on PA scores at 3 months. While the pandemic made PA difficult for many participants, these barriers were not associated with leisure-time PA levels or related theoretical mechanisms of action, which bodes well for the success of our ongoing intervention efforts and the resiliency of these communities.

RESUMEN

OBJECTIVE: To understand early-life growth in the Middle East and North Africa (MENA) region, and how it has changed over time, we estimated the prevalence of wasting and overweight at ages under 5 years. DESIGN: Cross-sectional data from twenty-nine Demographic and Health Surveys with direct anthropometric data and parent-reported demographic information were examined. The study utilised the WHO Child Growth Standards to classify overweight (weight-for-height z-score ≥ 2 sd above the median), wasting (weight-for-height z-score ≤ 2 sd below the median) and unhealthy weight defined as either wasting or overweight. SETTING: Nationally representative for nine of the MENA countries (Armenia, Azerbaijan, Egypt, Jordan, Mauritania, Morocco, Tunisia, Turkey and Yemen). PARTICIPANTS: Children under age 5 from nine MENA countries between 1987 and 2016 (n 155 961). RESULTS: Across the region, at the most recent time point, between 7·3 and 23·6 % of children experienced unhealthy weight (Jordan - 7·3 %, Egypt -23·6 %); 1·7 and 16·6 % had wasting (Turkey, Yemen) and 2·0 and 15·0 % had overweight (Yemen, Egypt). Overweight was more common than wasting in all countries except Yemen and Mauritania. Between 1987 and 2016, the prevalence of unhealthy weight in the region increased (10·0-18·4 %) due to increases in both wasting and overweight. Boys had a higher prevalence of unhealthy weight than girls. CONCLUSION: Undernutrition continues to be a problem in some countries in the MENA region, and overnutrition is emerging as a health concern in many countries in the region. Countries in the region must advance programmes that reduce undernutrition while not overlooking or inadvertently promoting overnutrition.

RESUMEN

Rates of non-alcoholic fatty liver disease (NAFLD) vary dramatically among Hispanic subpopulations, with Mexican-origin (MO) Hispanics experiencing a disproportionate burden. This study examined dietary fatty acid (FA) intake among overweight and obese MO Hispanic adults in the United States (US) and evaluated its association with liver steatosis and fibrosis. Participants (N = 285, MO Hispanic adults) completed 24-h dietary recalls to assess dietary FA exposure. Liver steatosis and fibrosis were estimated using transient elastography (FibroScan®). Multiple regression analysis tested relationships between FA intakes and liver steatosis or fibrosis, adjusting for age, sex, body mass index (BMI) and total energy. A total of 51% (n = 145) of participants were suspected to have NAFLD and 20% self-reported a type 2 diabetes diagnosis. No significant association was observed between Linoleic Acid and α-Linolenic Acid (LA:ALA) ratio, or omega-6 to omega-3 (n-6:n-3) ratio and liver steatosis. However, a one-point increase in the LA:ALA ratio resulted in a 1.01% increase in the liver fibrosis scores (95% CI: [1.00, 1.03]; p = 0.03), and a one-point increase in the n-6:n-3 ratio resulted in a 1.02% increase in liver fibrosis score (95% CI: [1.01, 1.03]; p = 0.01). Further research is needed to determine if modulation of FA intake could reduce NAFLD risk in this high-risk population.

RESUMEN

BACKGROUND: In the United States, the prevalence of obesity among adults has increased 3-fold since the 1980s, but patterns of incidence of new cases of obesity are not known. OBJECTIVES: To examine the incidence of new cases of obesity: overall, by demographic and educational subgroups, by weight status, and changes during this century. METHODS: We analyzed adult (≥20 y) anthropometric records from the US nationally representative Panel Study of Income Dynamics from 2001 to 2017. Among those not having obesity (body mass index, BMI, ≥30 kg/m2) at first observation, we used Poisson models to estimate the incidence of obesity [cases/1000 person-years (PYs)] and incidence rate ratio (IRR). RESULTS: Among 13,888 adults followed for 115,797 PYs, the incidence of obesity in 2001-2017 was 28.1/1000 PYs (95% CI: 26.7, 29.7). Over the periods 2001-2005, 2005-2009, and 2009-2013, the incidence of obesity was stable, but in 2013-2017 the incidence increased by 18% compared to 2009-2013 [IRR: 1.18 (95% CI: 1.06, 1.30)]. Blacks had higher obesity incidence [47.9/1000 PYs (95% CI: 42.7, 53.1)] than Whites [26.2/1000 PYs (95% CI: 24.6, 27.9)]. Risk was particularly high among Black females [57.9/1000 PYs (95% CI: 49.1, 66.8)] and Black young adults (20-29 y) [65.5/1000 PYs (95% CI: 54.2, 76.7)]. Across race, obesity incidence was highest in young adults (20-29 y) [34.1/1000 PYs (95% CI: 31.5, 36.7)] and declined with age [age 70+ y: 18.9/1000 PYs (95% CI: 16.6, 21.8)]. Those with overweight had an obesity risk 7 times higher than those with normal weight [62.1/1000 PYs (95% CI: 58.8, 65.3) vs. 8.8/1000 PYs (95% CI: 8.1, 9.6)]. Those with less than high-school education had higher obesity incidence than those with education beyond high-school [39.4/1000 PYs (95% CI: 34.4, 44.4) vs. 24.7/1000 PYs (95% CI: 23.1, 26.3)]. CONCLUSIONS: Incidence of obesity was stable over the first 13 y of the last 2 decades but increased by 18% in 2013-2017. Blacks and younger adults were at highest risk, and those with overweight were also at high risk for developing obesity.

RESUMEN

INTRODUCTION: British South Asians have a higher prevalence of overweight and obesity than the wider population. Bradford (UK), with its high Pakistani presence and levels of economic deprivation, has exceptionally high instances, especially in deprived areas where many Pakistanis reside. British Pakistani women in Bradford are more likely to be overweight and obese. There is uncertainty on how these women can be aided to manage their weight. Therefore, the objective of this study was to explore the obesity concerns of Pakistani women living in deprived inner-city areas of Bradford. METHODS: Three focus groups interviews were carried out with 23 Pakistani women living in deprived areas of Bradford. Data were analysed thematically. RESULTS: This exploratory study identified a wide range of concerns that women had around managing their weight. Participants disclosed distrust in information given around medication, conflicting dietary information and reported low levels of trust in women-only organized physical activities. Cultural barriers were identified, which included the gender role of the woman, the lack of culturally appropriate dietary advice, cultural misunderstandings of what constitutes a healthy diet and healthy weight, the lack of culturally suitable exercise facilities and conforming to family and community expectations. Other concerns were language barriers around a lack of understanding, the inability to read Urdu and reliance on others to translate information. CONCLUSION: These findings have implications for researchers, local authorities, policy makers and others with an interest in reducing the rates of obesity in this population. Recommendations include training health practitioners to be culturally aware of the diet and eating practices of this community, exploring different ways to support socially isolated women to be more physically active at home, addressing physical activity and diet misconceptions and designing obesity management information materials appropriate for a range of literacy levels. PATIENT OR PUBLIC CONTRIBUTION: Public contributors were involved in the development of the interview guide and design of the research. A pilot focus group with participants not included in the present paper was used to help test and refine the focus group questions. Interview transcripts were member checked by participants, and participants assisted with data analysis.

RESUMEN

ABSTRACT Objective To characterize food consumption, considering the degree of industrial food processing by public schools' adolescents. Methods Cross-sectional study involving adolescents aged 14 to 19 years, of both genders, attending public schools in Juiz de Fora, MG. Food consumption was assessed using two 24-hour dietary recalls. Foods were classified into three groups according to the degree of industrial processing: (1) unprocessed foods or minimally processed foods, culinary ingredients and preparations based on these foods; (2) processed foods; (3) ultra-processed foods. In addition, weight and height information was collected, with subsequent calculation of body mass index/age to assess the individuals' nutritional status according to the gender. Pearson's chi-square, Mann-Whitney and Kruskal-Wallis tests were performed, adopting a value of p<0.05. Results The sample consisted of 804 adolescents, with a predominance of females (57.5%). In the sample, 29.9% and 26.1%, of girls and boys, respectively, were overweight. There was a difference in the daily consumption of ready-made sweet-tasting foods, being higher in females (26.2%) when compared to males (18.1%), whereas the consumption of soft drinks (one to four times a week) was 47.2% and 55.6% in girls and boys, respectively (p<0.05). Higher consumption of ultra-processed foods was observed in females (p=0.02) and processed foods in males (p=0.008). Conclusion There was a high contribution of ultra-processed foods in the diet of adolescents in public schools; a high prevalence of overweight was observed in both genders.


RESUMO Objetivo Caracterizar o consumo alimentar através do grau de processamento industrial dos alimentos consumidos por adolescentes matriculados em escolas públicas. Métodos Estudo transversal com adolescentes de 14 a 19 anos de ambos os sexos matriculados em escolas públicas de Juiz de Fora, MG. O consumo alimentar foi avaliado através de dois recordatórios de 24h. Os alimentos foram classificados em três grupos de acordo com o grau de processamento industrial: (1) alimentos in natura ou minimamente processados, ingredientes culinários e preparações a base desses alimentos; (2) alimentos processados; (3) alimentos ultraprocessados. Ademais, foram coletadas informações de peso e altura dos estudantes, com posterior cálculo de índice de massa corporal/idade para avaliação do estado nutricional conforme o sexo. Foram realizados os testes Qui-quadrado de Pearson, Mann-Whitney e Kruskal-Wallis, adotando o valor de p<0,05. Resultados A amostra foi composta por 804 adolescentes, com predomínio do sexo feminino (57,5%). Entre os adolescentes, 29,9% das meninas e 26,1% dos meninos apresentaram excesso de peso. Observou-se diferença no consumo diário de alimentos prontos de sabor doce, sendo maior no sexo feminino (26,2%) quando comparado ao masculino (18,1%), ao passo que o consumo de refrigerantes de uma a quatro vezes na semana foi de 47,2% e 55,6% nas meninas e meninos, respectivamente (p<0,05). Maior consumo de alimentos ultraprocessados foi observado no sexo feminino (p=0,02) e de alimentos processados no sexo masculino (p=0,008). Conclusão Verificou-se elevada contribuição proveniente do grupo dos alimentos ultraprocessados na dieta dos adolescentes de escolas públicas, com altas prevalências de excesso de peso em ambos os sexos.

RESUMEN

ABSTRACT Objective The objective of the present study was to propose cutoff points of neck circumference for predicting overweight in Brazilian children. Methods We conducted a cross-sectional study with 875 children from public schools in Brazil. Weight, height, and neck circumference were measured. Nutritional status and the risk of complications were assessed based on the values of body mass index and neck circumference. Receiver operating characteristic curve analysis was used to verify the cutoff points. Results The median age was eight years, and the majority of the children had normal weights by body mass index and had no risk of metabolic complications by neck circumference. There was a correlation between neck circumference and body mass index (k=0.689; p<0.005). The mean values proposed for overweight were 29.2 cm for girls and 29.1 cm for boys. Conclusion Neck circumference had a good correlation with body mass index, and the cutoff points proposed can identify overweight in Brazilian children.

RESUMEN

ABSTRACT Objective To describe the nutritional profiles of children under five years of age in the state of Rondônia, comparing them with those from the Northern Region of Brazil and from Brazil. Methods This was a time series ecological study. Data were collected from the Food and Nutrition Surveillance System. The information concerned Body Mass Index by age, gender and place of residence. A time-trend analysis was performed using linear regression applying the Prais-Winsten technique and serial autocorrelation verification using the Durbin and Watson test in Stata®16.0. Results There was an annual increasing trend for the thinness, risk of overweight, overweight and obesity regardless of gender, age and location and for extreme thinness, with the exception of girls and for the age of 2 to 5 years, which revealed a stationary trend. Among boys and children of both genders under two years of age, annual growth trends were higher for non-eutrophic nutritional status when compared to the other groups. The growth rates of nutritional disorders found in the Northern region were higher than in the state of Rondônia and in Brazil. Conclusion It is necessary to review health policies aiming at the promotion and prevention of nutritional problems considering the current situation where extreme conditions such as thinness and obesity coexist, with special attention to male children under 2 years of age.

RESUMEN

BACKGROUND: Obesity and overweight affect a large proportion of the world's population. Increasingly, this problem can be observed among young adults. The aim of the study was to identify the motivations and barriers to healthy eating habits among young Poles, the relationship between physical activity and healthy eating and the impact of healthy eating on the body composition of the young. METHODS: The method used in the research was a diagnostic survey using direct personal interviews. The research was conducted in the years 2016-2019 on a group of 399 young Poles aged 18-26. Their body composition was analyzed by determining resistance and reactance using the biological impedance method, with a TANITA SC-330ST Body Composition Analyzer. RESULTS AND CONCLUSION: The main reasons for healthy eating among young Poles are the intent to follow a doctor's recommendations, to lose weight and to live a healthy lifestyle and to follow a trend. On the other hand, the largest barriers to proper nutrition are: lack of time to prepare healthy meals and of financial resources, inability to prepare meals and limited knowledge of the principles of healthy eating. The eating behavior varied significantly in relation to the physical activity of the respondents. Active people's eating habits were the best, and those of sedentary people the worst. Healthy eaters also had normal body composition indicators (adipose tissue level, BMI, body type). Young adults should be educated on the principles of healthy eating and have access to healthy food in canteens and vending machines, both at work and at university.

RESUMEN

The double burden of malnutrition (DBM) affects many low- and middle-income countries. However, few studies have examined DBM at the individual level, or undernutrition and overnutrition co-occurring within the same person. This study aims to investigate the prevalence and determinants of DBM among adults in the Philippines. Data from the 2013 National Nutrition Survey were used. The sample size in the analysis was 17,010 adults aged ≥20 years old, after excluding pregnant and lactating women. DBM was defined as the co-occurrence of overweight/obesity and anemia (definition #1), overweight/obesity and anemia or vitamin A deficiency (definition #2), and overweight/obesity and anemia or vitamin A deficiency or iodine insufficiency (definition #3). Anthropometric measurements and biochemical markers were used for DBM assessment. Data were analyzed using descriptive statistics, the chi-square test, and logistic regression by R software. Results showed that definition #3 is the predominant type of DBM (7.0%) in the general population, whereas the prevalence of DBM has increased to 23.7% in overweight/obese persons. Sex, age, educational attainment, marital status, household size, wealth quintile, and smoking status were the determinants of DBM. This study revealed that Filipino adults experience malnutrition critically and must be addressed through food and nutrition interventions.
