Associations between Age-Related Hearing Loss and DietaryAssessment Using Data from Korean National Health andNutrition Examination Survey.

Age-related hearing loss (ARHL) is a major and rapidly growing public health problem that causes disability, social isolation, and socioeconomic cost. Nutritional status is known to cause many aging-related problems, and recent studies have suggested that there are interaction effects between ARHL and dietary factors. We aimed to investigate the association between ARHL and dietary assessment using data from the fifth Korean National Health and Nutrition Examination Survey, which is a nationwide cross-sectional survey that included 5201 participants aged ≥50 years from 2010 to 2012. All participants had normal findings on otoscopic examination and symmetric hearing thresholds of <15 dB between both sides. Nutritional survey data included food consumption and nutrient intake using the 24 h recall method. Data were analyzed using multiple regression models with complex sampling adjusted for confounding factors, such as age, sex, educational level, and history of diabetes. Higher intake of seeds and nuts, fruits, seaweed, and vitamin A were positively associated with better hearing. Our findings suggest that dietary antioxidants or anti-inflammatory food may help reduce ARHL.

The Impact of Dietary Knowledge on Health: Evidence from the China Health and Nutrition Survey.

Promoting a healthy diet through education is part of the Healthy China 2030 action plan. However, studies examining how dietary knowledge affects public health in China are sparse. This study employs multiple waves of the China Health and Nutrition Survey (CHNS) data to examine the impacts of dietary knowledge on Chinese adults’ health, with a particular emphasis on how the impacts of dietary knowledge vary across different demographic groups. Moreover, we contribute to the literature by incorporating the spouse’s dietary knowledge into the analysis framework to inspect the relationship between a spouse’s dietary knowledge and an individual’s health. Our results indicate that dietary knowledge significantly improves an individual’s health status. However, there is no evidence that an individual’s health is influenced by his/her spouse’s dietary knowledge. Moreover, we find that individuals with a lower level of education and rural residents benefit more from increasing dietary knowledge. Policy implications of this study are also discussed.

Understanding nutritional intake of Chinese farmers from the perspective of sustainable livelihood analysis.

Based on the framework of sustainable livelihood analysis and using the China Health and Nutrition Survey (CHNS) data, this paper examines the connection between livelihood assets and farmers' nutritional intake. Results show that capital endowment and nutritional intake of farmers with diversified production are greater than those who specialize; capital endowment and nutritional intake of horticultural households are greater than those who engage in agriculture. Compared with non-economically disadvantaged households, higher livelihood assets have significant association with improved fat and protein intake of economically disadvantaged households. Compared with diversified farmers, more livelihood assets have significant association with improved energy and carbohydrate intake of agricultural households. Compared with those who specialize, additional livelihood assets have significant association with improved fat and protein intake of farmers with diversified production.

Factors Associated with Human Papillomavirus Non-vaccination: The National Health and Nutrition Survey

Objectives: The purpose of this study was to investigate the human papillomavirus (HPV) vaccination proportion and the factors associated with HPV non-vaccination according to the characteristics of Americans. Methods: The 2015-2018 National Health and Nutrition Survey (NHANES) data were analyzed. The subjects aged 9 to 26 were divided into subgroups according to age and sex. Results: The meaningful variables influencing HPV vaccination included birth country, health insurance, hepatitis A vaccine, hepatitis B vaccine, routine place to go for healthcare and times receive healthcare last year. The factors associated with HPV non-vaccination were income, hepatitis A vaccine, hepatitis B vaccine and times receive healthcare last year. Conclusions: This study was based on a survey of Americans, so the factors associated with HPV non-vaccination may differ from those of Koreans.

Sensory characteristics of vegetables consumed by Australian children.

Consumption is driven by children's sensory acceptance, but little is known about the sensory characteristics of vegetables that children commonly eat. A greater understanding could help design more effective interventions to help raise intakes, thus realising beneficial health effects. This study sought to: (1) Understand the vegetable consumption patterns in children, with and without potatoes, using the Australian and WHO definitions. (2) Describe the sensory characteristics of vegetables consumed by children by age group, level of intake and variety. (3) Determine the vegetable preferences of children, by age group, level of intake and variety. Analysis of National Nutrition Survey data, combining reported vegetable intake with sensory characteristics described by a trained panel. Australia. A nationally representative sample of Australian children and adolescents aged 2-17·9 years (n 2812). While consumption increased in older age groups, variety remained constant. Greater variety, however, was associated with higher vegetable consumption. Potato intake increased with consumption, contributing over one-third of total vegetable intake for highest vegetable consumption and for older age groups. Children favoured relatively sweet vegetables and reported lower consumption of bitter vegetables. There were no differences in the sensory properties of vegetables consumed by children in different age groups. After potatoes, carrots, sweetcorn, mixtures, fruiting and cruciferous types were preferred vegetables. Children tend to prefer vegetables with sensory characteristics consistent with innate taste preferences (sweet and low bitterness). Increasing exposure to a variety of vegetables may help increase the persistently low vegetable consumption patterns of children.

A recursive model of residual life prediction for human beings with health information from activities of daily living and memory

As the ageing population increases, it is essential to manage human resources with residual life prediction, especially for the ageing population. Thus, this study aims to predict residual life using the available information of health statuses, such as the performances in activities of daily living (ADL) and memory. In this study, the principal components of ADL and memory information are extracted for prediction. The relationship between the principal components and residual life is established based on the concept of the proportional residual, which states that the residual life may be proportional to the changes in ADL and memory performance. A recursive model for residual life prediction is formulated and fitted for the Chinese Health and Nutrition Survey data. Finally, a goodness-of-fit test is conducted, and an example case is presented. The results show that the fitted model in this study is more accurate and precise than the original, unfitted model to estimate the residual life of human beings. This study is advantageous over existing studies in two aspects: (1) the model is formulated using a recursive method based on stochastic filtering; (2) the data include both physical status and mental status.

The burden of excessive saturated fatty acid intake attributed to ultra-processed food consumption: a study conducted with nationally representative cross-sectional studies from eight countries.

Cross-sectional nutritional survey data collected in eight countries were used to estimate saturated fatty acid intakes. Our objective was to estimate the proportion of excessive saturated fatty acid intakes (>10 % of total energy intake) that could be avoided if ultra-processed food consumption was reduced to levels observed in the first quintile of each country. Secondary analysis was performed of 24 h dietary recall or food diary/record data collected by the most recently available nationally representative cross-sectional surveys carried out in Brazil (2008-9), Chile (2010), Colombia (2005), Mexico (2012), Australia (2011-12), the UK (2008-16), Canada (2015) and the US (2015-16). Population attributable fractions estimated the impact of reducing ultra-processed food consumption on excessive saturated fatty acid intakes (above 10 % of total energy intake) in each country. Significant relative reductions in the percentage of excessive saturated fatty acid intakes would be observed in all countries if ultra-processed food consumption was reduced to levels observed in the first quintile's consumption. The reductions in excessive intakes ranged from 10⋅0 % (95 % CI 6⋅2-13⋅6 %) in Canada to 35⋅0 % (95 % CI 28⋅7-48⋅0 %) in Mexico. In all eight studied countries, all presenting more than 30 % of intakes with excessive saturated fatty acids, lowering the dietary contribution of ultra-processed foods to attainable, context-specific levels was shown to be a potentially effective way to reduce the percentage of intakes with excessive saturated fatty acids, which may play an important role in the prevention of non-communicable diseases, particularly cardiovascular diseases.

Purpose : This study was to contribute to the establishment of a worker 's obesity management base by analyzing the factors affecting the obesity of the workers by gender by using the National Health and Nutrition Survey data. Methods : The data collected in this study used the SPSS 21.0 program and analyzed through chi-square test and multiple regression analysis. Results : Factors related to male obesity were employment type, working hours, alcohol and exercise, and factors related to female obesity were income and education levels. Conclusion : In order to lower the obesity of male workers, it is necessary to provide education for improvement of health behavior and to provide obesity management program for workers with irregular or long working hours, workers who have a high frequency of drinking or do not exercise. In order to lower the obesity of female workers, it is necessary to provide a customized obesity management program such as educating workers who have low income level or education level through counseling and education of practicable obesity management methods in the condition of the subject.

Trade liberalization and the health of working-age adults: Evidence from China

Abstract Past research has examined the effects of import competition on workers' health outcomes, but few studies have investigated the impact of export expansion. We take advantage of the exogenous changes in export tariffs on Chinese products after the Reform and Opening-Up policies in China to estimate the effect of reductions in export tariffs on the health of working-age adults. Using China Health and Nutrition Survey data from 1993 to 2009, we create individual-level panels and find that reductions in export tariffs improved the health of working-age adults. Analysis of possible mechanisms shows that reduced export tariffs led to increased earnings and hours worked as well as decreased malnutrition, suggesting an income effect driven by export-led growth. This conclusion is further supported by the observation of greater health improvements among those without urban residency and those with low educational attainment. The findings contribute to the limited evidence on this topic among developing economies as well as the ongoing discussion of the relationship between income and health.

The dynamic impact of income and income distribution on food consumption among adults in rural China

Previous studies have demonstrated that income has a significant effect on food demand in rural China. However, little research has focused on the dynamic impact of income and income distribution on food demand in rural China. Using China Health and Nutrition Survey data, this study employs a consistent two-step quadratic almost ideal demand system model, with addressed problems of endogeneity of total expenditure and zero shares, to estimate the food demand elasticities among adults in rural areas with regard to the different income strata. The results show that changes in income and income strata have significant effects on food demand in rural areas. Except for grains, all other food groups, including vegetables, oils and fats, animal products, and other foods, have positive income elasticities, and the rise in the income strata will lead to declining income elasticities for grains, vegetables, oils and fats, and animal products. Based on the estimated income elasticities, the food consumption projections indicate that reducing income inequality in rural society can improve the living standard of low-income people in terms of nutrient intakes.

Forecasting the Populations of Overweight and Obese Chinese Adults.

PurposeThe objective of this study was to forecast the prevalence rates and the populations of overweight and obese in Chinese adults for 2030.Materials and MethodsNine waves of China Health and Nutrition Survey (CHNS) data from 1991 to 2015 were used. A polynomial regression model was fitted to obtain the average BMI change trajectory of the population born in different years according to different sexes and residence areas (urban and rural). The model fitted to CHNS 2015 survey data was used to forecast the distribution of BMI and the prevalence rates of overweight and obesity in 15 years. The United Nations population forecast was then used to predict the proportions of overweight obese adults in all age groups in China in 2030.ResultsThe prevalence rates of overweight and obesity were projected to increase in both sexes and all geographic areas in future. By 2030, urban males will have the highest prevalence of overweight, 50.7% (95% CI: 47.5%, 53.9%). Except urban males, the prevalence of overweight and obesity in rural areas will exceed that in urban for both sexes. In 2030, the numbers of overweight and obese people in China aged 20–89 years will reach 540 million and 150 million, respectively, which are 2.8 and 7.5 times higher compared to prevalences in 2000. In 2030, the number of overweight and obese people in China aged 60–89 years will reach 200 million and 40 million, respectively, 6.3 and 8.5 times increments from the year 2000.ConclusionThe prevalence rates of overweight and obese in Chinese adults are projected to increase further, by 2030 more than half of adult males living in urban areas will be overweight. Combined with changes in the population age structure, overweight and obesity will have a huge impact on the health of the Chinese population over the next 15 years.

Effects of Obesity on Outcomes of Acute Type A Aortic Dissection Repair in Japan.

Background: The prevalence of obesity among Japanese acute type A aortic dissection (ATAAD) patients and its effect on repair outcomes remain to be elucidated.Methods and Results: The prevalence of obesity (body mass index [BMI] ≥30.0 kg/m2) among 1,059 patients (mean [±SD] age 64.3±12.7 years) who underwent ATAAD repair between 1990 and 2018 was compared with that among the general Japanese population (National Health and Nutrition Survey data). The prevalence of obesity among male patients (17.1% [6/35], 20.0% [18/90], and 14.4% [20/139] for those aged 20–39, 40–49, and 50–59 years, respectively) was significantly higher than that among the age- and sex-matched general population. The 1,059 patients were divided into groups according to weight (normal [BMI <25.0 kg/m2; n=742], overweight [BMI 25.0–29.9 kg/m2; n=248], or obese [BMI ≥30.0 kg/m2; n=69]). Comparing the normal weight, overweight, and obese groups revealed significant differences among the 3 groups in median cardiopulmonary bypass time (143, 167, and 183 min, respectively), ventilation >48 h (44.5%, 60.1%, and 78.3%, respectively), and in-hospital mortality (7.0%, 7.3%, and 17.4%, respectively), but not in 30-day survival. Shock, visceral malperfusion, operation time >360 min, obesity, and coronary malperfusion were identified as predictors of in-hospital mortality.Conclusions: The prevalence of obesity is increased among Japanese male patients with ATAAD aged ≤59 years. Obesity may increase these patients’ operative risk; overweight does not.

Self-reported sleep duration, sleep quality and sleep problems in Mexicans adults: Results of the 2016 Mexican National Halfway Health and Nutrition Survey

ObjectiveThis study aimed to investigate self-reported sleep duration, sleep quality and sleep problems in a Mexican adult population by considering age, sex, geographical regions and urban/rural residency. Design/MeasurementsCross-sectional national adult survey based on the 2016 Mexican National Halfway Health and Nutrition Survey data. SettingNationally representative survey data. ParticipantsMexican adults ≥ 18 years, n = 8649 (N weighted = 71,158,260 adults). ResultsOverall, mean sleep duration was 7:19 hours, from which 37% had sleep problems, and 45.7% reported very good sleep quality. Furthermore, middle-aged adults slept less than younger and older adults, females were at lower risk of being a short sleeper than males, urban residents slept less than rural residents, and those from the center region of the country slept less than from the northern and southern regions. Mainly, participants from the state of Quintana Roo, Aguascalientes, and Baja California reported sleep duration <7 hours (6:26 hours, 6:45 hours, and 6:55 hours, respectively). Overall Mexicans who obtained sufficient sleep (≥8 hours) were more likely to be female, in their 20s, reporting perceived "good" or "very good" sleep quality, possessed no self-reported sleep problems, were not a tobacco user, and resided in rural areas. Furthermore, Mexicans who obtained poor sleep quality were more likely to be females that reported sleep problems, took sleep medications, and resided in urban areas. ConclusionThe present study's findings have important implications for understanding the nationwide features of sleep in Mexican adults. Education and public health awareness initiatives regarding good sleep may be warranted.
