RESUMEN

BACKGROUND: Sarcopenia is an age-related, multifactorial syndrome. Previous studies have shown that air pollutants are associated with inflammation and oxidative stress. However, the association between long-term exposure to air pollution and sarcopenia is not completely understood. METHODS: The Taiwan National Health Research Database (NHIRD) contains medical records of almost all Taiwanese residents. Daily air pollution data collected by the Taiwan Environmental Protection Agency was used to analyze concentrations of sulfur oxide (SO2), carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2), and particulate matter (PM2.5, PM10). The databases were merged according to the insurants' living area and the location of the air quality monitoring station. We categorized the pollutants into quartiles (Q1, Q2, Q3, and Q4). RESULTS: Our study population consisted of 286,044 patients, among whom 54.9% were female and 45.1% were male. Compared to Q1 levels of pollutants, Q4 levels of SO2 (adjusted hazard ratio [aHR] = 8.43; 95% confidence interval [CI] = 7.84, 9.07); CO (aHR = 3.03; 95%CI = 2.83, 3.25); NO (aHR = 3.47; 95%CI = 3.23, 3.73); NO2 (aHR = 3.72; 95%CI = 3.48, 3.98); PM2.5 (aHR = 21.9; 95% CI = 19.7, 24.5) and PM10 (aHR = 15.6; 95%CI = 14.1, 17.4) increased risk of sarcopenia. CONCLUSIONS: Our findings indicated a significantly increased risk of sarcopenia in both male and female residents exposed to high levels of air pollutants.

RESUMEN

Objective:To investigate the prevalence of metabolic syndrome(MS) among adult residents with different characteristics and the relationship between serum uric acid(SUA) level and MS using the data of Chinese Adult Chronic Diseases and Nutrition Surveillance(2018) program in Anhui.Methods:Multi-stage stratified cluster random sampling was used to select participants aged 18 and over for questionnaires, physical measurements, and laboratory tests. The complex weighted method was used to estimate the prevalence of MS among residents with different characteristics. Logistic regression model based on complex sampling data was used to analyze the relationship between SUA and MS. Receiver operating characteristic(ROC) curve was used to evaluate the reliability of SUA in diagnosing MS and determine the optimal cutoff point.Results:A total of 7 182 participants were included and the prevalence of MS among adult residents was 29.46%. The prevalence of MS was higher in females(33.76%) than that in males(25.28%), and the difference was statistically significant( P<0.05). After adjusting for other factors, for every 10 μmol/L increase in SUA, the risk of MS increased by 4% in males( OR=1.040, 95% CI 1.019-1.061) and 7% in females( OR=1.070, 95% CI 1.059-1.082). The area under the curve(AUC) for SUA in diagnosing MS was 0.816(95% CI 0.806-0.826), with a sensitivity of 0.761 and specificity of 0.727. The optimal cutoff point for SUA was 450 μmol/L. Conclusion:The prevalence of MS among adult residents in Anhui Province is 29.46%. SUA is a risk factor for MS, and increasing SUA level indicated a higher risk of MS. The optimal cutoff value of SUA may be helpful in diagnosing MS.

OBJECTIVE: To analyze the age distribution of nutrition and health knowledge level of Chinese residents aged 18-64. METHODS: A total of 102 398 residents aged 18-64 were selected from 302 survey sites in China by multi-stage cluster random sampling method, a total of 98 567 respondents were included in the study. Both mean and rate were calculated by complex sampling weighting. RESULTS: The nutrition and health knowledge score of residents aged 18-24, 25-34, 35-44, 45-54 and 55-64 years old in China were(65.1±11.4) points, (64.6±11.7) points, (64.7±12.0) points, (62.2±12.8) points and(59.5±13.3) points. The nutrition and health knowledge awareness rates were 20.3%, 19.1%, 20.3%, 16.9% and 12.1%, respectively(P<0.001). A decreasing trend in all dimensions and overall nutrition and health knowledge with increasing age was found(ß<0, P_(trend)<0.001). This trend was also reflected across gender or regions. While the trend of nutrition and health knowledge level with age varies with different literacy levels. Differences in knowledge points with positive response rates <30% by age groups. CONCLUSION: The level of nutrition and health knowledge among Chinese adult residents of all ages is relatively low in 2021, but the knowledge shortcomings are different.

RESUMEN

An estimated one-fifth to one half (17.5%-50.5%) of the older adult residents living in long-term care facilities are either malnourished or at risk of malnourishment. Malnutrition in older adults is related to frailty, sarcopenia, anemia, falls, morbidity, and mortality. Monitoring nutritional status and instituting appropriate nutritional care plans in long-term care facilities can help prevent the development of disabilities in older adult residents and reduce long-term healthcare expenditures. In this article, after introducing the primary diagnostic tests for malnutrition, the three main nutritional care principles are presented in the following categories: non-specific health problems, specific-health problems, and dehydration are presented. Next, the behavioral-environmental factors of nutritional care are defined. Finally, the related challenges and practical recommendations are discussed.

RESUMEN

Objective: To study the relationship between eating behavior and obesity among Chinese adults. Methods: Data were collected from 171 040 people who had been engaged in the 2013 China Chronic and Non-communicable Disease and Risk Factors Surveillance project. Rao-Scott χ(2) test and complex sampling design were used to compare the differences in the rates of eating behavior and obesity. A binary logistic regression model based on complex sampling design was used to investigate the relationship between eating behavior at three meals (breakfast, lunch and dinner) and obesity. Results: The proportion (3.3%) of skipping breakfast appeared the highest. Proportions of eating out for all the three meals were 16.4%, 21.4% and 11.7%, respectively. The prevalence rates of obesity among men who ate lunch at home, ate out or skipped the lunch were 13.2%, 16.1% and 15.9%, respectively. The prevalence rates of obesity among women who ate lunch at home, ate out or skipped lunch were 14.5%, 9.8%, 19.6%, respectively. Results from the multivariate logistic regression analysis showed that eating out for lunch and skipping lunch were both positively correlated with obesity in men (eating out for lunch: OR=1.10, 95%CI: 1.02-1.18; skipping lunch: OR=1.36, 95%CI: 1.02-1.80) while skipping lunch was positively associated with obesity (OR=1.47, 95%CI:1.07-2.02) in women. No statistical association was noticed between eating out for lunch and obesity in women, with OR=0.86 (95%CI: 0.73-1.00). Both eating out for dinner and skipping dinner were positively correlated with obesity in men, with eating out for lunch as OR=1.19 (95%CI: 1.06-1.34) and skipping dinner as OR=1.89 (95%CI: 1.07-3.33). Avoid dinner was positively associated with obesity in women, with OR=1.64 (95%CI: 1.02-2.63). Women who ate out for dinner showed lower risk of obesity than those who ate at home with OR=0.74 (95%CI: 0.59-0.94). Conclusions: Different eating behaviors were seen in Chinese adults, with the highest proportion of eating out for lunch and the lowest proportion for dinner. Both eating out for lunch and dinner appeared risk factors of obesity in men while avoid lunch or dinner were both associated with obesity in both sex.

RESUMEN

OBJECTIVE: To understand the sleep conditions of adults in Shandong Province. METHODS: From 2010 to 2012, 10 201 residents aged ≥6 years old were selected from 7 counties and cities in Shandong Province by multi-stage stratified cluster sampling method in proportion to the population. A face-to-face interview was conducted with a questionnaire uniformly formulated by "China National Nutrition and Health Surveillance"to investigate and analyze the sleep status of residents aged 18 years and above. RESULTS: A total of 6626 people over the age of 18 were investigated. The average daily sleep was(7. 84±1. 29) h. There was no significant difference between male((7. 80 ± 1. 07) h) and female((7. 86 ± 1. 18) h). However, there was significant difference between males((7. 87±1. 17) h) and females((8. 01±1. 27) h) in rural areas(t = 3. 08, P < 0. 01). There was significant difference in different regions(big cities(7. 62± 1. 17) h, small and medium-sized cities(7. 85 ± 0. 89) h, rural areas(7. 95 ±1. 23) h, F = 39. 733, P<0. 001) and in different age groups(18-44 years old(7. 97±0. 98) h, 45-49 years old(7. 80±1. 07) h, 60 years old and above(7. 74±1. 33) h, F =21. 642, P<0. 001), the average daily sleep time was decreased with increasing age. The insufficient sleep rate was 9. 8%, there was no significant different between male(9. 5%)and female(10. 1%). There was significant difference in different regions(big cities15. 3%, small and medium-sized cities 5. 2%, rural areas 9. 7%, χ~2= 105. 870, P <0. 001) and in different age groups(18-44 years old 5. 1%, 45-59 years old 9. 7%, 60 years old and above 15. 3%, χ~2= 114. 308, P < 0. 001). Big cities had the higher insufficient sleep rate than medium-sized cities and rural areas, The insufficient sleep rate showed an upward trend with the increase of age. The proportion of excessive sleep was9. 3%. The difference between male(8. 4%) and female(10. 0%) was statistically significant(t = 2. 11, P < 0. 05). There were statistically significant differences in different regions(7. 0% in large cities, 6. 0% in medium and small cities, 12. 8% in rural areas, χ~2= 77. 156, P< 0. 01) and different, age groups(6. 7% in 18-44 years old, 6. 1% in 45-59 years old, 16. 8% in 60 years old and above, χ~2= 175. 556, P <0. 01). The rate of excessive sleep in rural areas was higher than that in cities, and the rate of excessive sleep in the 45-59 age group was the highest. CONCLUSION: Insufficient sleep is common in adult residents in Shandong Province. The insufficient sleep is more significant among elderly population and residents of big cities. The problem of excessive sleep also exists.

RESUMEN

OBJECTIVE: To determine the associations between sleep duration and hypertension in Chinese adults. METHODS: This longitudinal study analyzed 9851 adults who had participated in at least two rounds of the CHNS (China Health and Nutrition Survey) during 2004-2011. Sleep duration was classified into ≤7, 8, and ≥9 h. Age, sex, residence location, education level, smoking, drinking alcohol, drinking tea, drinking coffee, activity level, and body mass index were adjusted as confounders in a generalized linear mixed model. RESULTS: The unadjusted analysis showed that compared with a normal sleep duration (8 h), the odds ratios (ORs) for those with short (≤7 h) and long (≥9 h) sleep durations were 1.24 and 1.17, respectively (95% confidence intervals [CIs] = 1.14-1.36 and 1.06-1.29). After adjusting for confounding factors, the effect of a short sleep duration on hypertension was still statistically significant, with an OR of 1.13 (95% CI = 1.04-1.24), while a long sleep duration no longer had a statistically significant effect. CONCLUSIONS: A short sleep duration is an independent risk factor for adult hypertension, whereas a long sleep duration is not in Chinese adults. The prevalence of hypertension should be prevented and controlled by improving the sleep status of adults.

RESUMEN

INTRODUCTION: Common mental disorders include depression, anxiety and somatoform disorders are a public health problem in developed as well as developing countries. It represents a psychiatric morbidity with significant prevalence, affecting all stages of life and cause suffering to the individuals, their family and communities. Despite this fact, little information about the prevalence of common mental illness is available from low and middle-income countries including Ethiopia. The aim of this study was to determine the magnitude of common mental disorders and its associated factors among adult residents of Harari Region. METHODS: Comparative cross-sectional, quantitative community-based survey was conducted From February 1, 2016 to March 30, 2016 in Harari Regional State using multi-stage sampling technique. A total of 968 residents was selected using two stage sampling technique. Of this 901 were participated in the study. Validated and Pretested Self reported questionnaire (SQR_20) was used to determine the maginitude of common mental disorders. Data was entered and analyzed using Epi-info version 3.5.1 and SPSS-17 for windows statistical packages. Univirate, Bi-variate and multivariate logistic regression analysis with 95% CI was employed in order to infer associations. RESULTS: The prevalence of common mental illnesses among adults in our study area was 14.9%. The most common neurotic symptoms in this study were often head ache (23.2%), sleep badly (16%) and poor appetite (13.8%). Substance use like Khat chewing (48.2%), tobacco use (38.2%) and alcohol use (10.5%) was highly prevalent health problem among study participant. In multivariate logistic regression analysis, respondents age between 25-34 years, 35-44 years, 45-54 years and above 55years were 6.4 times (AOR 6.377; 95% CI: 2.280-17.835), 5.9 times (AOR 5.900; 95% CI: 2.243-14.859), 5.6 times (AOR 5.648; 95% CI: 2.200-14.50) and 4.1 times (AOR 4.110; 95% CI: 1.363-12.393) more likely having common mental illnesses than those age between 15-24 years, respectively. The occurrence of common mental illness was twice (AOR: 2.162; 95% CI 1.254-3.728) higher among respondents earn less than the average monthly income than those earn more than average monthly income. The odds of developing common mental illnesses were 6.6 times (AOR 6.653; 95% CI: 1.640-6.992) higher among adults with medically confirmed physical disability than those without physical disability. Similarly, adults who chewed Khat were 2.3 times (AOR 2.305; 95% CI: 1.484-3.579) more likely having common mental illnesses than those who did not chew Khat. Adults with emotional stress were twice (AOR 2.063; 95% CI: 1.176-3.619) higher chance to have common mental illnesses than adults without emotional stress. CONCLUSION: This study had reveals that common mental disorders are major public health problems. Advancing age, low average family monthly income, Khat chewing and emotional stress were independent predictors of common mental illnesses. Whereas sex, place of residence, educational status, marital status, occupation, family size, financial stress, taking alcohol, tobacco use and family history of mental illnesses were not statistically associated with common mental illnesses.

OBJECTIVE: To understand dairy consumption characteristics among adult residents in nine provinces of China. METHODS: Using the 9 rounds data from the "China health and nutrition survey "( CHNS) on the subjects aged 18 to 59 years old with complete 24-hour-dietary for 3 days, analyze dairy consumption rate, average dairy intake and variation characteristics, and compare with the Chinese residents ' dietary guidelines recommended. RESULTS: There were increasing trends of dairy consumption rate and average daily intake among adult residents from 1989-2011, in which dairy consumption rate rose from 1. 45% in 1989 g/d to 16. 84% in 2011. The average dairy intake rose from 2. 06 g/d in 1989 to 26. 47 in 2011. The rate of the average dairy intake more than300 g/d( the recommended dairy intake of the dietary guidelines for Chinese people) rose from 0. 12% in 1989 to 1. 13% in 2011. CONCLUSION: The condition of dairy consumption among Chinese adult residents was improved significantly, but there was still huge gap with the 300 g/d proposed by the Chinese residents' dietary guidelines.

RESUMEN

BACKGROUND: Manganese (Mn) inhalation has been associated with neuropsychological and neurological sequelae in exposed workers. Few environmental epidemiologic studies have examined the potentially neurotoxic effects of Mn exposure in ambient air on motor function and hand tremor in adult community residents. Mn exposed residents were recruited in two Ohio towns: Marietta, a town near a ferro-manganese smelter, and East Liverpool, a town adjacent to a facility processing, crushing, screening, and packaging Mn products. METHODS: Chronic (≥ 10 years) exposure to ambient air Mn in adult residents and effects on neuropsychological and neurological outcomes were investigated. Participants from Marietta (n=100) and East Liverpool (n=86) were combined for analyses. AERMOD dispersion modeling of fixed-site outdoor air monitoring data estimated Mn inhalation over a ten year period. Adult Mn-exposed residents' psychomotor ability was assessed using Finger Tapping, Hand Dynamometer, Grooved Pegboard, and the Computerized Adaptive Testing System (CATSYS) Tremor system. Bayesian structural equation modeling was used to assess associations between air-Mn and motor function and tremor. RESULTS: Air-Mn exposure was significantly correlated in bivariate analyses with the tremor test (CATSYS) for intensity, center frequency and harmonic index. The Bayesian path analysis model showed associations of air-Mn with the CATSYS non-dominant center frequency and harmonic index; while the Bayesian structural equation model revealed associations between air-Mn and lower Finger Tapping scores. Household income was significantly associated with motor dysfunction but not with tremor. CONCLUSION: Tremor and motor function were associated with higher exposure to airborne Mn.

Objective To establish the reference intervals of serum pepsinogen(PG)in healthy adults in Changsha area,and to explore their distribution as well as related factors.Methods Serum PGⅠand PGⅡ levels were determined by a latex-enhanced turbidimetric immunoassay method in 1 279 subjects from Changsha area.Then PGⅠ/PGⅡ was calculated.Results The PGⅠ, PGⅡ and PGⅠ/PGⅡ levels of 1 279 healthy adult residents showed a skew distribution.The levels of serum PGⅠand PGⅠ/PGⅡ in males were 62.0 ng/mL and 4.3,which in females were 59.4 ng/mL and 4.1,significantly lower than those in males(P<0.05).Age was significantly positive correlated with serum concentrations of PGⅡ(r= 0.278,P<0.01),and was negative correla-ted with PGⅠ/PGⅡratio(r= -0.173,P<0.01).The normal reference ranges of serum PGⅠ,PGⅡ and PGⅠ/PGⅡ in males were≥56.8 ng/mL,≤22.6 ng/mL,and ≥3.3,respectively,and in females were ≥51.4 ng/mL,≤23.1 ng/mL,and ≥3.0,respec-tively.Conclusion The serum PG levels of healthy adult residents significantly show skew distributions in Changsha area,which are affected by gender and age.The establishment of reference intervals of PG contributes to clinical screening and diagnosis of gas-tric-related deseases.

RESUMEN

BACKGROUND: Kano State is the most populous state, and one of those states pronounced with the highest prevalence of drug abuse in Nigeria. However, there is lack of documented data to back the assertion. OBJECTIVE: We determined the pattern, awareness and perceptions of the adult residents of Kano metropolis about self medication. MATERIALS AND METHODS: We used a descriptive cross-sectional design to study a random sample of 380 adult in Kano metropolis. Data was collected using semi-structured questionnaires that were pretested outside the study area. Data analysis was with Epi Info® 3.5.1. RESULTS: The mean age of the subjects was 35.43 ± 15.10 years, majority were males (66.32%), singles (47.11%) and had at least secondary education (67.63%). About three-quarter (78.95%) admitted using drug (s) in the past without prescription. Drugs commonly consumed were antimalarials (42.10%), analgesics (40.56%), antibiotics (29.41%), and cough mixtures (13.31%). Common sources of drugs were patent medicine stores (62.54%) and the market (19.81%). Common reasons for self medication were long queues in the hospitals (38.39%), and in-accessibility to doctors (25.08%). About two-thirds (65.00%) correctly perceived that self medication could be hazardous; and half (51.58%) were aware of at least one hazard of self medication. CONCLUSION/RECOMMENDATIONS: Irrational drug use is a growing challenge to public health in Kano, Nigeria. Thus, drug regulatory agencies in Nigeria should work together to ensure that all drug retail outlets and drug sellers are registered, controlled drugs are dispensed only on prescription of the physicians; and the laws safeguarding drug use are duly enforced. Health authorities should also strengthen efforts towards health educating the public.

RESUMEN

Objective To understand hypertension risk factors among adult residents in Hebei province.Methods The adult residents were selected by multistage stratified sampling,and investigated with the same questionnaires,body measurement,blood pressure measurement,blood sample analysis,to analyze risk factors of hypertension by ?2 with simple factor and by logistic regression with mult-factors.Results The prevalence of hypertension in 4200 adult residents(18-69 ages) was 39.6% and age-adjusted rate was 28.5%.The single factors analysis indicated that the prevalence of hypertension was higher in men than in women,in countryside than in city,and increased with age rising.Its prevalence is correlated with education level,marriage status,occupation,income,smoking,passive smoking,manual activity,eating habits,BMI,waist,diabetes,blood fat,status of spirit and health.Multiple logistic regression analysis indicated that city,female,educational level of senior high school and above that,farm working,eating less brined vegetables is protective factors for hypertension,and their OR(95%CI) were 0.777(0.644~0.937),0.674(0.551~0.823),0.654(0.534~0.801),0.826(0.684~0.997),0.844(0.729~0.977) respectively,and more than 35 ages,not usually eating vegetable,bad status of health by self-sensations,high serum TC and TG,overweight and obesity were the main risk factors for hypertension,and their OR(95%CI) were 4.145(3.263~5.266),4.460(1.049~18.969),1.234(1.068~1.425),1.400(1.200~1.634),1.420(1.074~1.878),1.478(1.235~1.768),1.728(1.448~2.061) respectively.Conclusion The prevalence of hypertension in adult residents in Hebei province was correlated with multi-factors,so complicated prevention and control in hypertension should be reinforced.
