RESUMO
BACKGROUND: Aging is an inevitable biological process. Accelerated aging renders adults more susceptible to chronic diseases and increases their mortality rates. Previous studies have reported the relationship between lifestyle factors and phenotypic aging. However, the relationship between intrinsic factors, such as reproductive factors, and phenotypic aging remains unclear. METHODS: This study utilized data from the National Health and Nutrition Examination Survey (NHANES), spanning from 1999 to 2010 and 2015-2018, with 14,736 adult women. Random forest imputation was used to handle missing covariate values in the final cohort. Weighted linear regression was utilized to analyze the relationship between women-specific reproductive factors and PhenoAgeAccel. Considering the potential impact of menopausal status on the results, additional analyses were conducted on premenopausal and postmenopausal participants. Additionally, the Life's Essential 8 (LE8) was used to investigate the impact of healthy lifestyle and other factors on the relationship between women-specific reproductive factors and PhenoAgeAccel. Stratified analyses were conducted based on significant interaction p-values. RESULTS: In the fully adjusted models, delayed menarche and gynecological surgery were associated with increased PhenoAgeAccel, whereas pregnancy history were associated with a decrease. Additionally, early or late ages of menopause, first live birth, and last live birth can all negatively impact PhenoAgeAccel. The relationship between women-specific reproductive factors and PhenoAgeAccel differs between premenopausal and postmenopausal women. High LE8 scores positively impacted the relationship between certain reproductive factors (age at menarche, age at menopause, age at first live birth, and age at last live birth) and phenotypic age acceleration. Stratified analysis showed significant interactions for the following variables: BMI with age at menarche, pregnancy history, and age at menopause; ethnicity with age at menopause, age at first live birth, and parity; smoking status with use of contraceptive pills and gynecologic surgery; hypertension with use of contraceptive pills, pregnancy history, and age at menopause. CONCLUSION: Delayed menarche, gynecological surgery, and early or late ages of menopause, first live birth, and last live birth are associated with accelerated phenotypic aging. High LE8 score may alleviate the adverse effects of reproductive factors on phenotypic aging.

BACKGROUND: The occurrence and progression of asthma can be influenced by the components in food. Our study aims to determine whether dietary antioxidant and inflammatory potential are associated with the risk of mortality in asthma patients. METHODS: Participants from the 2001-2018 National Health and Nutrition Examination Survey (NHANES) aged 20 years and older with a diagnosis of asthma were included. Mortality status was obtained according to death certificate records from the National Death Index. The antioxidant and inflammatory potential of the diet was assessed using two widely used and dependable indices, Composite Dietary Antioxidant Index (CDAI) and Dietary Inflammatory Index (DII). Restricted cubic spline (RCS) regression was used to analyze the non-linear relationship between the two indexes and mortality. Multivariable Cox proportional risk models were used to estimate hazard ratio and 95% confidence intervals for mortality. Finally, the relationship between CDAI and DII was analyzed. RESULTS: A total of 4698 NHANES participants represented 23.2 million non-institutionalized residents of the US were enrolled in our study. Patients with higher CDAI or lower DII exhibited longer survival times. RCS regression showed a linear relationship of CDAI or DII with mortality. In the Cox regression, both crude and adjusted models demonstrated that higher CDAI or lower DII was linked to a reduced risk of all-cause mortality. Similar associations were found in subgroup analysis. Finally, a negative relationship was found between CDAI and DII. CONCLUSION: Reducing pro-inflammatory or increasing antioxidant diets could reduce all-cause mortality among adult asthma patients.

INTRODUCTION: The Weight-Adjusted Waist Index (WWI) is a new indicator of obesity that is associated with all-cause mortality in Asian populations. Our study aimed to investigate the linear and non-linear associations between WWI and all-cause mortality in non-Asian populations in the United States, and whether WWI was superior to traditional obesity indicators as a predictor of all-cause mortality. METHODS: We conducted a cohort study using data from the 2011-2018 National Health and Nutrition Examination Survey (NHANES), involving 18,592 participants. We utilized Cox proportional hazard models to assess the association between WWI, BMI, WC, and the risk of all-cause mortality, and performed subgroup analyses and interaction tests. We also employed a receiver operating characteristics (ROC) curve study to evaluate the effectiveness of WWI, BMI, and WC in predicting all-cause mortality. RESULTS: After adjusting for confounders, WWI, BMI, and WC were positively associated with all-cause mortality. The performance of WWI, BMI, and WC in predicting all-cause mortality yielded AUCs of 0.697, 0.524, and 0.562, respectively. The data also revealed a U-shaped relationship between WWI and all-cause mortality. Race and cancer modified the relationship between WWI and all-cause mortality, with the relationship being negatively correlated in African Americans and cancer patients. CONCLUSIONS: In non-Asian populations in the United States, there is a U-shaped relationship between WWI and all-cause mortality, and WWI outperforms BMI and WC as a predictor of all-cause mortality. These findings may contribute to a better understanding and prediction of the relationship between obesity and mortality, and provide support for effective obesity management strategies.

BACKGROUND: Limited data regarding the correlation between oxidative balance score (OBS) and hyperuricemia highlights the necessity for thorough investigations. This study aims to examine the link between OBS, which incorporates dietary and lifestyle factors, and the occurrence of hyperuricemia. METHODS: We conducted a cross-sectional study involving 13,636 participants from the 2007-2018 National Health and Nutrition Examination Survey (NHANES). The oxidative balance score (OBS) was determined based on four lifestyle factors and sixteen dietary nutrients. We assessed the levels of serum uric acid (SUA) and the occurrence of hyperuricemia as outcomes. Weighted logistic regression and linear models were used for statistical analysis, using Restricted Cubic Splines (RCS) to examine potential nonlinear associations. Subgroup analysis and sensitivity assessments were performed to identify any variations and ensure the robustness of the findings. RESULTS: Higher OBS was consistently correlated with decreased SUA levels and a reduced prevalence of hyperuricemia. RCS highlighted a significant negative nonlinear association, particularly in females. Subgroup analysis revealed gender-based differences and interactive correlation, providing additional insights regarding OBS and hyperuricemia relationship. CONCLUSION: This study underscores a robust negative correlation between OBS and SUA levels as well as the incidence of hyperuricemia, emphasizing the importance of dietary and lifestyle factors. Incorporating RCS, subgroup analysis, and sensitivity assessments enhances the depth of our findings, providing valuable insights for further research.

BACKGROUND: Parkinson's disease (PD) is a slowly progressive neurodegenerating disease that may eventually lead to disabling condition and pose a threat to the health of aging populations. This study aimed to explore the association of two potential risk factors, selenium and cadmium, with the prognosis of Parkinson's disease as well as their interaction effect. METHODS: Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2005-2006 to 2015-2016 and National Death Index (NDI). Participants were classified as Parkinson's patients by self-reported anti-Parkinson medications usage. Cox regression models and restricted cubic spline models were applied to evaluate the association between PD mortality and selenium intake level as well as blood cadmium level. Subgroup analysis was also conducted to explore the interaction between them. RESULTS: A total of 184 individuals were included. In full adjusted cox regression model (adjusted for age, gender, race, hypertension, pesticide exposure, smoking status and caffeine intake), compared with participants with low selenium intake, those with normal selenium intake level were significantly associated with less risk of death (95%CI: 0.18-0.76, P = 0.005) while no significant association was found between low selenium intake group and high selenium group (95%CI: 0.16-1.20, P = 0.112). Restricted cubic spline model indicated a nonlinear relationship between selenium intake and PD mortality (P for nonlinearity = 0.050). The association between PD mortality and blood cadmium level was not significant (95%CI: 0.19-5.57, P = 0.112). However, the interaction term of selenium intake and blood cadmium showed significance in the cox model (P for interaction = 0.048). Subgroup analysis showed that the significant protective effect of selenium intake existed in populations with high blood cadmium but not in populations with low blood cadmium. CONCLUSION: Moderate increase of selenium intake had a protective effect on PD mortality especially in high blood cadmium populations.

BACKGROUND: The aging global population is experiencing escalating challenges related to cognitive deficits and dementia. This study explored the interplay between pulmonary function, physical activity, and cognitive function in older U.S. adults to identify modifiable risk factors for cognitive decline. METHODS: Utilizing NHANES 2011-2012 data, we conducted a cross-sectional analysis of 729 participants aged ≥ 60 years. Cognitive function, peak expiratory flow (PEF), and physical activity were assessed. Weighted logistic regression and mediation analyses were employed to examine associations. RESULTS: The sample size was 729 (weighted mean [SD] age, 67.1 [5.3] years; 53.6% female participants). Preliminary correlation analysis indicated a positive correlation between the global cognitive score and physical activity (ß = 0.16; p < 0.001), recreational activity (ß = 0.22; p < 0.001), and PEF in percent predicted (PEF%) (ß = 0.18; p < 0.001). Compared to those with a PEF% >100%, the PEF% (80-100%) group (OR, 2.66; 95% CI, 1.34-5.29; p = 0.005) and PEF% <80% group (OR, 3.36; 95% CI, 1.67-6.76; p = 0.001) were significantly associated with higher cognitive deficits risk. Recreational activity meeting guidelines was linked to a lower risk of cognitive deficits (OR, 0.24; 95% CI, 0.10-0.57; p = 0.001). Mediation analysis demonstrated that PEF mediates the relationship between physical activity and cognitive function. CONCLUSION: This study revealed significant associations between lower PEF, diminished physical activity, and increased cognitive deficits in elderly individuals. The results supported the hypothesis that pulmonary function may mediate the connection between activity and cognitive health, emphasizing the importance of respiratory health in cognitive aging. Recognizing these associations is crucial for clinical care and public health policy aiming to mitigate cognitive decline in aging populations. While these findings are intriguing, validation through longitudinal design studies is deemed necessary.

ABSTRACT Objective This study aims to build geographic models related to the nutritional status of adolescents and describe territories regarding the prevalence of malnutrition, overweight, and obesity, in order to spatially represent how the nutritional status of adolescents is distributed in the city. Methods Using geocoding techniques, graphic models were built using data from the SISVAN platform, as well as the addresses and nutritional status of adolescents aged 10 to 19 years in the municipality of Divinópolis, in the state of Minas Gerais (Brazil), between 2020 and 2021. Results There was a prevalence of 34% of obesity and overweight in the 2020 and 2021 samples. The graphical models showed that there is no specific pattern of points for the spread of nutritional diagnoses, but it was possible to identify areas of heat and places with a higher concentration of overweight. Underweight had a homogeneous spread and did not stand out in the formation of profiles. Conclusion Geographic tools with the adolescents' nutritional profile were successfully modeled, which have the potential to contribute to better health indicator management in the assessed territory, even with the limitations of the study.
RESUMO Objetivo Este trabalho tem como objetivo construir modelos geográficos relativos ao perfil nutricional de adolescentes e descrever territórios quanto à prevalência de déficit de peso e excesso de peso, de modo a representar espacialmente como o diagnóstico nutricional de adolescentes está distribuído na área estudada. Métodos Através da técnica de geocodificação foram construídos modelos gráficos utilizando a plataforma SISVAN, os endereços e o estado nutricional de adolescentes de 10 a 19 anos do município de Divinópolis, Minas Gerais, nos anos de 2020 e 2021. Resultados Houve prevalência de 34% de excesso de peso na amostra de 2020 e 2021. Os modelos gráficos mostraram que não há um padrão específico de pontos de propagação dos diagnósticos nutricionais, porém foi possível identificar áreas de calor e locais de maior concentração de excesso de peso. O déficit de peso teve um espalhamento homogêneo e não se destacou na formação de perfis. Conclusão Foi possível modelar ferramentas geográficas com o perfil nutricional dos adolescentes, as quais têm potencial de contribuir para a melhor gestão de indicadores de saúde no território avaliado, mesmo com as limitações do estudo.

Vitamin B12 deficiency poses a health concern, especially in vulnerable populations. Dietary vitamin B12 intake was obtained by two 24 h dietary recalls and food propensity questionnaires in a representative Slovenian cross-sectional food consumption survey, SI.Menu (n = 1248 subjects; 10-74 years). For a subgroup of 280 participants, data on serum vitamin B12 were available through the Nutrihealth study. The estimated usual population-weighted mean daily vitamin B12 intakes were 6.2 µg (adults), 5.4 µg (adolescents), and 5.0 µg (elderly). Lower intakes were observed in females. Inadequate daily vitamin B12 intake (<4 µg) was detected in 37.3% of adolescents, 31.7% of adults, and 58.3% elderlies. The significant predictors for inadequate daily vitamin B12 intake were physical activity score in all age groups, sex in adolescents and adults, financial status and smoking in elderly, and employment in adults. Meat (products), followed by milk (products), made the highest vitamin B12 contribution in all age groups. In adolescents, another important vitamin B12 contributor was cereals. The mean population-weighted serum vitamin B12 levels were 322.1 pmol/L (adults) and 287.3 pmol/L (elderly). Low serum vitamin B12 concentration (<148 nmol/L) and high serum homocysteine (>15 µmol/L) were used as criteria for vitamin B12 deficiency. The highest deficiency prevalence was found in elderlies (7.0%), particularly in males (7.9%). Factors associated with high serum homocysteine were also investigated. In conclusion, although vitamin B12 status was generally not critical, additional attention should be focused particularly to the elderly.

Em pacientes críticos o risco nutricional e a hiperglicemia associam-se ao aumento da incidência de desfechos desfavoráveis. Objetivo: Avaliar a relação do risco nutricional pelo Nutrition Risk in Critically III, versão modificada (mNUTRIC) e perfil glicêmico nos desfechos de alta, óbito e tempo de internação de pacientes críticos e verificar o impacto das ferramentas Acute Physiology and Chronic Health Disease Classification System II (APACHE II) e do Sepsis-Related Organ Failure Assessment (SOFA) nesses desfechos. Método: Estudo longitudinal prospectivo desenvolvido em Unidade de Terapia Intensiva (UTI). Foram incluídos adultos, com tempo ≥ 48 horas de internação e com registro mínimo de duas aferições glicêmicas. Excluíram-se pacientes em cuidados paliativos, readmitidos nas UTI e gestantes. O teste Exato de Fisher e Shapiro Wilk foram utilizados para avaliar as variáveis categóricas e contínuas, respectivamente. Posteriormente, utilizou-se o teste de Mann-Whitney ou t-Student não pareado. Realizou-se análise de regressão logística e linear. O nível de significância adotado foi de 5%. Resultados: Ao avaliar 35 pacientes, 45,7% apresentaram alto risco nutricional. Foi observado associação do risco nutricional com os desfechos de alta e óbito; o SOFA associou-se ao óbito e tempo de internação. O incremento de 1 ponto no escore do SOFA aumentou a chance de óbito em 83% e tempo maior de internação em 0,49 dias. O perfil glicêmico e APACHE II não se associou aos desfechos. Conclusão: o escore SOFA foi o instrumento que apresentou associações significativas com o desfecho do óbito e maior tempo de internação de pacientes críticos
In critically ill patients, nutritional risk and hyperglycemia are associated with an increased incidence of unfavorable outcomes. Objective: To evaluate the relationship of nutritional risk by the Nutrition Risk in Critically III, modified version (mNUTRIC) and glycemic profile in the outcomes of discharge, death and length of stay in critically ill patients and to verify the impact of the Acute Physiology and Chronic Health Disease Classification System II (APACHE II) and the Sepsis-Related Organ Failure Assessment (SOFA) tools on these outcomes. Method: Prospective longitudinal study developed in an Intensive Care Unit (ICU). Adults were included, with ≥ 48 hours of hospitalization and with a minimum record of two blood glucose measurements. Patients in palliative care, readmitted to ICU and pregnant women were excluded. Fisher's Exact test and Shapiro Wilk test were used to evaluate categorical and continuous variables, respectively. Subsequently, the Mann-Whitney or unpaired t-Student test was used. Logistic and linear regression analysis was performed. The significance level adopted was 5%. Results: When evaluating 35 patients, 45.7% were at high nutritional risk. An association was observed between nutritional risk and discharge and death outcomes; SOFA was associated with death and length of hospital stay. The increment of 1 point in the SOFA score increased the chance of death by 83% and a longer hospital stay by 0.49 days. Glycemic profile and APACHE II were not associated with outcomes. Conclusion: the SOFA score was the instrument that showed significant associations with the outcome of death and longer hospital stay in critically ill patients

ABSTRACT Objective This study aimed to evaluate the memorization of messages that promote healthy eating, as well as satisfaction and feasibility of a nutritional intervention using a mobile text messaging app aimed at adolescents from public schools in the Federal District, Brazil. Methods The messages sent addressed aspects of healthy eating based on the Dietary Guidelines for the Brazilian Population. A self-reported questionnaire was applied with 94 students to assess the memorization of the messages received during the nutritional intervention, the level of satisfaction with the intervention, whether the messages were read and shared, the frequency of reading, and what was learned from the intervention. The association of memorization with satisfaction and with the frequency of reading the messages was also investigated. Results About 48% of participants reported remembering at least one message; 77.7% showed high ranges of satisfaction; 54.3% always read the messages; 66.0% did not share messages with other people. Most of the students reported positive learning or good impressions about the intervention. An association was found between memorization and satisfaction with the intervention (p=0.002), as well as between reading and memorization (p=0.005). Conclusion Although the memorization of the healthy eating messages sent in the nutritional intervention was less than expected, a great satisfaction and high frequency of reading the messages were reported by adolescents. Future studies should investigate the permanence of the results of long-term nutrition intervention, the main influencers of memorization, and how to improve it.
RESUMO Objetivo Este estudo teve como objetivo avaliar a memorização de mensagens de promoção de alimentação adequada e saudável, a satisfação e a usabilidade de uma intervenção nutricional via aplicativo direcionada para adolescentes de escolas públicas do Distrito Federal. Métodos As mensagens enviadas abordavam aspectos sobre alimentação adequada e saudável com base no Guia Alimentar para a População Brasileira. Foi aplicado um questionário de autopreenchimento a 94 estudantes para avaliar a memorização das mensagens recebidas durante a intervenção nutricional, o nível de satisfação com a intervenção, se as mensagens eram lidas e compartilhadas, a frequência de leitura e quais foram os aprendizados decorrentes da intervenção. Investigou-se ainda a associação entre a memorização, a satisfação e a frequência de leitura das mensagens. Resultados Cerca de 48% dos participantes referiram lembrar de pelo menos uma mensagem da intervenção; 77,7% se mostraram satisfeitos com o estudo; 54,3% sempre liam as mensagens que recebiam e 66% não compartilhava as mensagens com outras pessoas. A maioria relatou aprendizados ou impressões positivas sobre a intervenção. Foi encontrada uma associação entre a memorização das mensagens e a satisfação com o estudo (p=0,002), bem como entre a leitura e a memorização das mensagens (p=0,005). Conclusão Apesar de a memorização das mensagens enviadas na intervenção nutricional ter sido aquém do esperado, foi referida grande satisfação e alta frequência de leitura pelos adolescentes. Futuros estudos devem investigar a permanência dos resultados de intervenções nutricionais a longo prazo, os principais influenciadores da memorização e como melhorá-la.

Background: Acrylamide is a well-known potential carcinogenic compound formed as an intermediate in the Maillard reaction during heat treatment, mainly from high-temperature frying, and is found in baked goods and coffee, as well as resulting from water treatment, textiles and paper processing. The effects of acrylamide on lung disease in humans remains unclear. We aimed to investigate the association between blood acrylamide and glycidamide and chronic obstructive pulmonary disease (COPD) in the United States of America (U.S.) population using PROC logistic regression models. Results: 2744 participants aged 20 to 80 from the 2013-2016 National Health and Nutrition Examination Survey (NHANES) were enrolled. After adjusting for demographic data, health factors and serum cotinine, the ratio of HbGA to HbAA (HbGA/HbAA) significantly increased the risk of COPD (P for trend = 0.022). The odds ratio (OR) with a 95% confidence interval (95% CI) for HbGA/HbAA in the third tile was 2.45 (1.12-5.31), compared with the lowest tile. The restricted cubic spline (RCS) curve showed a positive linear correlation between the log (HbGA/HbAA) and the risk of COPD (P = 0.030). Conclusion: The ratio of glycidamide and acrylamide (HbGA/HbAA) was associated with COPD. This association was more prominent in males, obese individuals, people with a poverty income ratio (PIR) < 1.85 or people who never exercise. However, null associations were observed between HbAA, HbGA and HbAA + HbGA, and COPD.

Little is known about the macronutrient intake status of adult Chinese people. This cross-sectional study assessed the macronutrient intake status of adults (aged ≥20 years) by comparing their intake level of macronutrients against the Dietary Reference Intakes (DRI). It further explored the associations between macronutrient intake status and age groups, genders, education levels, smoking status, drinking frequency, social classes, knowledge of Chinese Dietary Guidelines 2016 (CDGs), healthy diet priorities, and areas (urban and rural) within two regions (northern and southern). The analysis includes the dietary intake data of 7860 Chinese adults, with complete data entries in the China Health and Nutrition 2011 survey. Dietary data were obtained through the 24 h recall method. More than half had carbohydrate intake below the recommended level of intake, and more than half had fat intake above the recommended level of intake. There were significant associations between three macronutrient intakes and education levels, social classes, healthy diet priorities, areas, and regions. Disparities in macronutrient consumptions revealed geographical and socioeconomic variations in dietary patterns, as well as risks for many different noncommunicable diseases. Public health and nutrition interventions should take notice of regional differences in dietary intake and place more emphasis on vulnerable populations including women, rural residents, and people with lower education level.

INTRODUCTION: Objective: active or passive tobacco use affects a high percentage of individuals and is associated with various health risks. The aim of this review was to look more closely at the nutritional problems that are specific of smokers, which may harm their health. Methods: a bibliographic search related to the topic. Results: smokers consume lower amounts of various foods, especially fruits, vegetables, cereals and dairy. As a result, their intake of vitamins, minerals, and phytochemicals is lower than that observed in non-smokers. Their consumption of meat, caffeine and alcohol is usually higher, and their activity lower than those of non-smokers, coexisting in smokers unhealthy behaviors that contribute to harming their health and quality of life. Oxidative stress and metabolic changes render the needs for some nutrients higher in smokers to achieve the same biochemical situation as in non-smokers. Recommended intakes of vitamin C have increased, but it will probably be necessary to also increase the intakes of other nutrients. In general, smokers suffer from deficiencies more frequently (vitamins C, E, ß-carotene, B1, B2, B12, folic acid, calcium, magnesium, iron, iodine, etc.) than non-smokers. Passive smokers are also affected in their eating habits and nutritional status. Conclusions: the worse nutritional status of smokers can contribute to the appearance/worsening of various diseases associated with smoking (cardiovascular, cancer, cataracts, osteoporosis, etc.); therefore, nutritional surveillance and correction of nutritional deficiencies could represents health benefits for smokers and passive smokers, which should be considered in the future.
INTRODUCCIÓN: Objetivos: el consumo de tabaco, activo o pasivo, afecta a un elevado porcentaje de individuos y se asocia a diversos riesgos sanitarios. Profundizar en los problemas nutricionales específicos de los fumadores que pueden contribuir a perjudicar su salud constituye el objeto de la presente revisión. Métodos: búsqueda bibliográfica en relación con el tema. Resultados: los fumadores consumen cantidades inferiores de diversos alimentos, especialmente: frutas, verduras, cereales y lácteos. Como consecuencia, su ingesta de vitaminas, minerales y fitoquímicos es inferior a la observada en los no fumadores. Su consumo de carne, cafeína y alcohol suele ser superior y su actividad inferior a la de los no fumadores, coexistiendo en los fumadores conductas poco saludables que se potencian, perjudicando la salud y la calidad de vida del colectivo. El estrés oxidativo y los cambios metabólicos hacen que las necesidades de algunos nutrientes sean superiores en los fumadores para lograr la misma situación bioquímica que en los no fumadores. Las ingestas recomendadas de vitamina C se han incrementado, pero probablemente sea necesario aumentar las de otros nutrientes. En general, los fumadores sufren deficiencias con más frecuencia (vitaminas C, E, ß-caroteno, B1, B2, B12, ácido fólico, calcio, magnesio, hierro, yodo, etc.) que los no fumadores. Los fumadores pasivos se ven afectados también en sus hábitos alimentarios y su situación nutricional. Conclusiones: la peor situación nutricional de los fumadores puede contribuir a la aparición/el empeoramiento de diversas patologías asociadas al hábito de fumar (cardiovasculares, cáncer, cataratas, osteoporosis, etc.), por lo que la vigilancia nutricional y la corrección de las deficiencias nutricionales podrían suponer un beneficio sanitario para los fumadores y fumadores pasivos que debe ser considerada en el futuro.

Childhood cancer survivors (CCSs) are at increased risk of developing chronic health conditions. This may potentially be reduced by a balanced diet. We aimed to compare dietary intake and diet quality using the Alternative Healthy Eating Index (AHEI) of adult CCSs and the general Swiss population. A food frequency questionnaire (FFQ) was completed by CCSs with a median age of 34 (IQR: 29-40) years. We compared dietary intake of 775 CCSs to two population-based cohorts who completed the same FFQ: 1276 CoLaus and 2529 Bus Santé study participants. CCSs consumed particular inadequate amounts of fiber and excessive amounts of sodium and saturated fat. Dietary intake was similar in CCSs and the general population. The mean AHEI was low with 49.8 in CCSs (men: 47.7, women: 51.9), 52.3 in CoLaus (men: 50.2, women: 54.0), and 53.7 in Bus Santé (men: 51.8, women: 54.4) out of a maximum score of 110. The AHEI scores for fish, fruit, vegetables, and alcohol were worse in CCSs than in the general population, whereas the score for sugar-sweetened beverages was better (all p < 0.001). Diet quality at follow-up did not differ between clinical characteristics of CCSs. Long-term CCSs and the general population have poor dietary intake and quality in Switzerland, which suggests similar population-based interventions for everyone.

BACKGROUND: Increasing coffee intake was inversely associated with risk of type 2 diabetes in Western countries. However, in China where coffee consumption and diabetes population has been growing fast in recent years, studies on the impact of coffee intakes on the onset of type 2 diabetes are lacking. This study attempts to determine the associations between coffee consumption and type 2 diabetes in Chinese adults. METHODS: This longitudinal study analyzed 10447 adults who had participated in at least two rounds of the China Health and Nutrition Survey (CHNS), which is a survey database of multistage, random cluster process during 1993-2011. Coffee consumption and type 2 diabetes incidence were measured in the survey. Body mass index (BMI), age, sex, place of residence, waves, education level, smoking, drinking alcohol and tea drinking frequency were adjusted as covariate. We used longitudinal fixed effects regression models to assess changes within person. RESULTS: After adjusting confounding factors, lower risk of diabetes is observed among Chinese adults who drink coffee occasionally (Adjusted Odds Ratio (AOR) = 0.13, 95% CI = 0.05, 0.34) and drink almost every day (AOR = 0.61, 95% CI = 0.45, 0.83), compared with those who do not or hardly drink. In the subgroup analysis, among women aged 45-59 who drink coffee one to three times a week (AOR = 0.21, 95% CI = 0.08, 0.52) and men over 60 who drink coffee almost every day (AOR = 0.19, 95% CI = 0.07, 0.53), protective effects were found. For young men aged 19-29, drinking coffee almost every day showed a risk effect (AOR = 20.21, 95% CI = 5.96-68.57). CONCLUSIONS: Coffee drinking habit is an independent protective factor for adult on type 2 diabetes in China. And it varies among people with different ages and genders. The rapid growth of coffee consumption in China in recent years may help reduce the risk of type 2 diabetes, but at the same time, the risk of type 2 diabetes in adolescents needs attention.

1,3-Butadiene is a volatile organic compound with a gasoline-like odour that is primarily used as a monomer in the production of synthetic rubber. The International Agency for Research on Cancer has classified 1,3-butadiene as a human carcinogen. We assessed 1,3-butadiene exposure in the U.S. population by measuring its urinary metabolites N-acetyl-S-(3,4-dihydroxybutyl)-L-cysteine (34HBMA), N-acetyl-S-(1-hydroxymethyl-2-propenyl)-L-cysteine (1HMPeMA), N-acetyl-S-(2-hydroxy-3-butenyl)-L-cysteine (2HBeMA), and N-acetyl-S-(4-hydroxy-2-buten-1-yl)-L-cysteine (4HBeMA). Urine samples from the 2011 to 2016 National Health and Nutrition Examination Survey were analysed for 1,3-butadiene metabolites using ultrahigh-performance liquid chromatography/tandem mass spectrometry. 34HBMA and 4HBeMA were detected in >96% of the samples; 1HMPeMA and 2HBeMA were detected in 0.66% and 9.84% of the samples, respectively. We used sample-weighted linear regression models to examine the influence of smoking status (using a combination of self-reporting and serum-cotinine data), demographic variables, and diet on biomarker levels. The median 4HBeMA among exclusive smokers (31.5 µg/g creatinine) was higher than in non-users (4.11 µg/g creatinine). Similarly, the median 34HBMA among exclusive smokers (391 µg/g creatinine) was higher than in non-users (296 µg/g creatinine). Furthermore, smoking 1-10, 11-20, and >20 cigarettes per day (CPD) was associated with 475%, 849%, and 1143% higher 4HBeMA (p < 0.0001), respectively. Additionally, smoking 1-10, 11-20, and >20 CPD was associated with 33%, 44%, and 102% higher 34HBMA (p < 0.0001). These results provide significant baseline data for 1,3-butadiene exposure in the U.S. population, and demonstrate that tobacco smoke is a major exposure source.

BACKGROUND: Information on long-term dietary intake is often required for research or program planning, but surveys routinely use short-term assessments such as 24-h recalls (24HRs). Methods to reduce the impact of within-person variation in 24HRs, such as the National Cancer Institute (NCI) method, typically require extensive training and skill. OBJECTIVES: We introduce the Simulating Intake of Micronutrients for Policy Learning and Engagement (SIMPLE) macro, a new tool to increase the accessibility of 24HR analysis. We explain the underlying theory behind the tool and provide examples of potential applications. METHODS: The SIMPLE macro connects the core NCI statistical code to estimate usual intake distributions and includes additional code to enable advanced analyses such as predictive modeling. The related SIMPLE-Iron macro applies the full probability method to estimate inadequate iron intake, and the SIMPLE-1D macro is used for descriptive or modeling analyses of data with a single 24HR per person. The macros and associated documentations are freely available. We analyzed data from the US National Health and Nutrition Examination Survey (NHANES) and the Cameroon National Micronutrient Survey to compare the SIMPLE macro to 1) the core NCI code using the Estimated Average Requirement cut point method, and 2) the IMAPP software for iron only, and to demonstrate the applications of the SIMPLE macro for estimating usual intake and predictive modeling. RESULTS: The SIMPLE macro generates identical results to the core NCI code. The SIMPLE-Iron macro also produces estimates of inadequate iron intake comparable to the IMAPP software. The examples demonstrate application of the SIMPLE macro to 1) descriptive analyses of nutrient intake from food and supplements (NHANES), and 2) analyses accounting for breast-milk nutrient intake and modeling fortification and supplementation programs (Cameroon). CONCLUSIONS: The SIMPLE macros may facilitate the analysis and modeling of dietary data to inform nutrition research, programs, and policy.

BACKGROUND: Hypertension is a common disease found in 1.13 billion adults worldwide. Several animal studies have provided evidence of the joint effect of alcohol drinking and cadmium exposure on hypertension. However, no epidemiologic study has examined the association between these 2 risk factors and hypertension. Therefore, we examined the individual effects of alcohol drinking and cadmium and the joint effect of their coexposure on hypertension in the general population. METHODS: We analyzed data from 8,403 South Korean adults who had been randomly assigned to the Korea National Health and Nutrition Examination Survey from 2008 to 2013. Multiple linear and logistic regression analyses were conducted to estimate the association of alcohol drinking and blood cadmium concentration with blood pressure and the odds ratio (OR) for hypertension. RESULTS: The weighted prevalence of hypertension and high-risk drinking was 25.7 and 13.6%, respectively. The weighted geometric mean of blood cadmium levels was 0.94 µg/L (95% confidence interval [CI]: 0.93 to 0.96). After adjusting for demographic characteristics, anthropometric measurements, health-related behaviors, and dietary and disease variables, the OR for hypertension in the group with the high-risk alcohol drinking was 1.67 (95% CI: 1.34 to 2.06) compared with the group without high-risk alcohol drinking. When the highest and the lowest blood cadmium quartiles were compared, the OR for hypertension was 1.46 (95% CI: 1.15 to 1.86). The positive joint effect of high-risk drinking and blood cadmium levels was statistically significant for systolic blood pressure (SBP; p = 0.037) and diastolic blood pressure (DBP; p < 0.001). CONCLUSIONS: Our results show that heavy alcohol drinking had a joint effect with cadmium exposure to increase the risk of hypertension. Future efforts are needed to reduce alcohol drinking and environmental cadmium exposure to prevent hypertension in the general population.

ABSTRACT: To date research investigating the associations between handgrip strength and multimorbidity when stratifying by age and sex is limited. Furthermore, this is the first study in a Korean population, and the first to include adults ≥â19 years of age. Here we investigated the associations between handgrip strength and multimorbidity in Korean adults aged ≥â19 years.In this cross-sectional study data from the Korean National Health and Nutrition Examination Survey were used. Multimorbidity was defined as having 2 or more chronic diseases. A total of 19,779 participants were eligible for the study (8730 male and 11,049 female). We grouped and analysed participants based on age and sex (men and women aged 19-49 years, men and women aged 50-80 years) and examined the associations between handgrip strength and multimorbidity using multivariate logistic regressions using stratification by age, sex and body mass index (BMI).Multivariate logistic regressions revealed a significant inverse association irrespective of sex, between relative handgrip strength and multimorbidity. Participants with the lowest handgrip strength had a significantly higher odds ratio (OR) of multimorbidity (men aged 19-49 years: 3.76 and aged 50 years to 80 years: 2.11; women aged 19 years to 49 years: 1.52 and aged 50-80 years: 2.15) when compared to those with highest handgrip strength after adjusting for confounding variables. The highest OR was observed in men aged 19 years to 49 years with a BMI ≥â25âkg/m2.In the current study we observed a significant inverse relationship between handgrip strength and multimorbidity in males and females with 2 or more chronic diseases. Male participants with a low handgrip strength aged between 19 years to 49 years with a BMI ≥25âkg/m2 may be at greater risk of multimorbidity. This study highlights the need for further longitudinal studies to investigate the effects of increasing handgrip strength combined with weight loss, as an effective strategy to reduce the incidence of multimorbidity.

PURPOSE: The purpose of the study was to investigate the prevalence of poor health behaviors (low dietary quality, low physical activity (PA), and high body mass index (BMI)) in cancer patients and the general population and its relationship with receipt of patient-physician recommendations. METHODS: We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2005-2014 to compare 1846 patients with a history of cancer to 16,641 with no cancer history. BMI was measured during physical exam. Dietary quality and PA were obtained from a questionnaire, along with receipt of physician recommendations for each behavior. RESULTS: Cancer patients had dietary quality that "needs improvement," were not meeting PA recommendations, and were overweight. Compared to the general population, dietary quality (54 vs. 54, p = .80), prevalence of physical inactivity (34% vs. 31%, p = .01), and BMI (28 vs. 28, p < .01) were similar. Among cancer patients, prevalence of physician recommendations to improve dietary quality (33.5%), increase PA or exercise (47.7%), and lose or control weight (32.1%) were low. Physicians recommended health behavior change to cancer patients more frequently than the general population (p < .01). Overweight and physically inactive cancer patients were more likely to receive physician recommendations (ps < .01). Physician recommendations were not associated with dietary quality (p = .65). CONCLUSIONS: Prevalence of poor diet, physical inactivity, and obesity is high in both populations with less than 50% of patients receiving physician health behavior recommendations. These findings underscore the need for increased frequency and efficacy of patient-physician health behavior recommendations, especially in cancer patients, to improve patient outcomes.
