Project description:BackgroundShort stature is a global health-related problem and remains to be evaluated in children in Hainan Province. The present study was conducted to investigate the associated factors with short-stature in children.MethodsThis cross-sectional study was conducted using a staged, cluster random sampling method. A total of 26,189 children aged 3-18 years, originating from 18 cities and counties in Hainan Province, to determine the prevalence of short stature. Additionally, these children were selected for a thorough analysis of associated factors.ResultsThe crude prevalence of short stature was 2.88%, and the standard prevalence was (after adding weights) 3.01%. Children's short stature was significantly related to seven factors: area, birth weight, body mass index z score (BAZ), maternal education, family income (RMB per year), frequency of bean intake and frequency of egg intake. A nomogram model of factors associated with short stature was constructed. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was 0.698 (95% CI: 0.679-0.716).ConclusionsOur findings demonstrated that birth weight, BAZ, dietary habits, and family-related factors were strongly correlated with short stature in children in Hainan Province.
Project description:There are few latest researches about induced abortion in China. We aimed to evaluate the prevalence of induced abortion and the related factors, thereby helping make targeted policies and measures to promote women's health. Three comparable cross-sectional surveys among Chinese women aged 18–49 years were performed in 2016, 2017, and 2021. A total of 14,573 eligible respondents were included in the study. 16.70% (95%CI 16.10%-17.31%) of respondents self-reported having experienced induced abortion, while 6.88% (95%CI 6.46%-7.29%) self-reported repeat induced abortion. Age range of 25–49 years (aOR 2.27–6.31, all P<0.05), living in western (aOR 1.72, 95%CI 1.50–1.98) and central (aOR 1.36, 95%CI 1.21–1.52) regions, having children (aOR 2.85, 95%CI 2.35–3.46) were associated with higher prevalence of induced abortion. Moreover, age range of 25–49 years, living in western and central regions, having children were also related to higher prevalence of repeat induced abortion (aOR 1.67–11.52, all P<0.05). Conversely, educational level of college or higher, household annual income over 80,000 Chinese yuan were associated with lower prevalence of induced abortion and repeat induced abortion (aOR 0.52–0.80, all P<0.05). Induced abortion remains noticeable in China. Sustained efforts are required to reduce unintentional pregnancy, improve reproductive health and post-abortion care services, and promote women's health.
Project description:ObjectiveWith the rapid development of the Chinese economy, Xiaoshan District, Zhejiang Province has experienced urbanisation, population ageing and significant lifestyle changes, so diabetes mellitus (DM) has attracted more attention. This study aimed to evaluate the prevalence of DM and its risk factors among individuals aged 18 years and above in the district.Study design and methodsA community-based cross-sectional study was carried out in Xiaoshan, China from 1 March to 31 August 2018. A multistage sampling method was used. Sociodemographic and behavioural characteristics were collected using a combination of centralised surveys and household surveys. Anthropometric parameters were measured with standardised techniques and calibrated equipment. Venous blood samples were obtained after at least 8 hours of fasting to determine the level of fasting blood glucose (FBG) and blood lipids. A standard 2-hour 75 g oral glucose tolerance test was also given if 6.1 mmol/L≤FBG<7.0 mmol/L. Univariate and multivariate logistic regression analyses were used to assess the associated factors of DM.ResultsThe overall prevalence of DM was 12.47%, and the proportion of previously undiagnosed DM (UDM) was 48.66%. The prevalence of pre-diabetes was 10.92%. Age, family history of DM (FHDM), obesity, abdominal obesity, systolic blood pressure (SBP), triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) were significantly associated with DM.ConclusionsThis study found a high prevalence of DM and pre-diabetes, especially a high prevalence of UDM among adults. The associated risk factors identified for DM were age, FHDM, obesity, abdominal obesity, SBP, TG and HDL-C.
Project description:ObjectivesTo describe the prevalence of modifiable risk factors for upper digestive tract cancer (UDTC) and its coprevalence, and investigate relevant influencing factors of modifiable UDTC risk factors coprevalence among residents aged 40-69 years in Yangzhong city, China.DesignCross-sectional study.ParticipantsA total of 21 175 participants aged 40-69 years were enrolled in the study. 1962 subjects were excluded due to missing age, marital status or some other selected information. Eventually, 19 213 participants were available for the present analysis.Main outcomes measuresPrevalence and coprevalence of eight modifiable UDTC risk factors (overweight or obesity, current smoking, excessive alcohol consumption, insufficient vegetables intake, insufficient fruit intake and the consumption of pickled, fried and hot food) were analysed.ResultsThe prevalence of overweight/obesity, current smoking, excessive alcohol consumption, insufficient vegetables intake, insufficient fruit intake and the consumption of pickled, fried and hot food in this study was 45.3%, 24.1%, 16.2%, 66.1%, 94.5%, 68.1%, 36.0% and 88.4%, respectively. Nearly all (99.9%) participants showed one or more UDTC risk factors, 98.6% of the participants showed at least two risk factors, 92.2% of the participants had at least three risk factors and 69.7% of the participants had four or more risk factors. Multivariate logistic regression analysis revealed that men, younger age, single, higher education, higher annual family income and smaller household size were more likely to present modifiable UDTC risk factors coprevalence.ConclusionsThe prevalence and coprevalence of modifiable UDTC risk factors are high among participants in Yangzhong city. Extra attention must be paid to these groups who are susceptible to risk factors coprevalence during screening progress. Relative departments also need to make significant public health programmes that aim to decrease modifiable UDTC risk factors coprevalence among residents aged 40-69 years from high-risk areas of UDTC.
Project description:IntroductionHealth literacy is an effective strategy to promote more cost-effective use of health care services and a crucial tool for preventing the spread of infectious diseases. The main objective of this study was to analyze changes in health literacy from 2019 to 2021.MethodsData were from the latest three-round cross-sectional studies with the same study design.ResultsAlthough the prevalence of adequate health literacy rose significantly over time, increasing from 26.9% (95% CI 20.1-33.7) in 2019 to 34.1% (32.9-35.3) in 2021, it was still at a relatively low level. The most significant decrease was observed for health skills among the three aspects and health information literacy among the six dimensions. Working as medical staff was a protective factor for adequate health literacy, health skills literacy, and health information literacy. Risk factors for adequate health literacy and health information literacy were older age and lower education level. Furthermore, adequate health information literacy was positively related to annual family income.DiscussionMore practical and effective policies targeting health literacy for critical aspects and groups in Central China, are urgently needed, especially during the epidemic.
Project description:BackgroundThe reference values of eNO have certain differences among people of different countries and races. We aimed to obtain the reference value of eNO in healthy children and adolescents (6-18 years old) in China and to explore the associations between the reference values with ages, gender, heights, BMI, and regions.MethodsWe measured FeNO50 levels in 5949 healthy Chinese children and adolescents, FeNO200 and CaNO levels in 658 participants from 16 provinces of 7 administrative areas in China aged 6-18. All persons were studied after obtaining informed consent from children and their parents.ResultsThe mean FeNO50 of 5949 Chinese children and adolescents aged 6-18 years was 14.1 ppb, with a 95% confidence interval of 1-38.1 ppb. The mean FeNO200 of 658 persons was 6.9 ppb with a 95% upper confidence interval of 15.0 ppb, and the mean CaNO was 3.0 ppb with a 95% upper confidence interval of 11.2 ppb. In the 6-11 age group, age and height were correlated with the logarithm of FeNO50 (P < 0.001, P < 0.05). There was no significant correlation between the logarithm of FeNO200 and gender, age, height and BMI (all P > 0.05). The logarithm of CaNO was correlated with gender (P < 0.05). In the 12-18 age group, gender, height, and region were correlated with the logarithm of FeNO50 (all P < 0.001). There was only a weak correlation between the logarithm of FeNO200 and height (P < 0.001). The logarithm of CaNO was negatively correlated with age (P < 0.05).ConclusionsHigher FeNO50, FeNO200 and CaNO values were found in healthy children and adolescents in China compared with foreign reports, and is affected by age, height, gender, and region. This study provides useful references for clinical application of eNO in children, especially Asian children.
Project description:BackgroundIn geriatric and long-term care settings, intertrigo seems to be common, but generalizable epidemiological estimates are lacking. Aim of this study was to measure the prevalence of intertrigo in aged nursing home residents and to identify possible relationships with demographic and health characteristics.MethodsA cross-sectional prevalence study was conducted between September 2014 and May 2015 in a random sample of ten institutional long-term care facilities in Berlin, Germany. In total 223, aged long-term care residents were included. Mean age was 83.6 (SD 8.0) years and mean Barthel score was 45.1 (SD 23.8). Board certified dermatologists and study assistants performed skin assessments and measurements according to standard operating procedures. Mean differences and odds ratios between residents with and without intertrigo were calculated.ResultsThe prevalence of intertrigo was 16.1% (95% CI 11.6 to 21.2%). The submammary fold was most often affected (9.9%), followed by the inguinal region (9.4%), axilla (0.5%) and abdominal region (0.5%). Increased age was statistically significantly associated with the presence of intertrigo (OR 1.05; 95% CI 1.00 to 1.10). Care dependency in bathing activities was associated with intertrigo. Obesity, sex and skin functional parameters were not associated with intertrigo.ConclusionsEvery sixth nursing home resident was affected by intertrigo indicating the high load of this skin condition in this population. Older age seems to be associated with intertrigo. Care dependency in bathing activities was likely to be associated with intertrigo. Structured skin care regimens are needed to prevent and treat intertrigo in this population.Trial registrationThis study is registered at https://clinicaltrials.gov/ct2/show/NCT02216526 .

Project description:ObjectiveHypertension (HTN) is an important public health issue worldwide, associated with the rapid economic development and urbanisation over the last decades. This is especially the case in Shenzhen, which has benefited greatly from the reform and opening-up policies. However, there is limited information on the epidemiology of HTN in this region. This study was designed to investigate the prevalence, awareness, treatment and control of HTN and the associated factors among adult residents in Shenzhen, China.DesignPopulation-based, cross-sectional study.ParticipantsThrough the multistage stratified random sampling method, a representative sample of 10 043 urban population aged ≥18 years were selected. Three consecutive blood pressure (BP) readings were measured after resting for a 5 min seat by trained staff and HTN was defined as mean systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg and/or self-reported current use of antihypertensive drugs. Participants were interviewed using a structured questionnaire. Anthropometric details, BP, blood and urine samples were also collected.Primary outcome measurePrevalence of HTN.ResultsOverall, the weighted prevalence of HTN among residents in Shenzhen was 19.2% (95% CI 18.5 to 20.0). Among patients with HTN, 55.0% (95% CI 52.9 to 57.1) were aware of their condition and 44.9% (95% CI 42.8 to 47.1) were taking antihypertensive medications, but only 21.7% (95% CI 20.0 to 23.5) achieved BP control. Among those who knew their HTN, 81.7% (95% CI 79.3 to 83.8) were under treatment and 48.3% (95% CI 45.1 to 51.5) were controlled among those with treated HTN. Male, older age, lower educational level, overweight and obesity, family history of HTN, tobacco smoking, alcohol intake, diabetes mellitus, dyslipidaemia and high uric acid were associated with HTN.ConclusionsHTN is a major public health concern in Shenzhen, which has low awareness, treatment and control rates, and is associated with several risk factors. Effective multifaceted implementation strategies are highly needed to combat the emerging burden of HTN.
Project description:ObjectiveWe aimed to assess hypertension prevalence and management in Central China.MethodsIn this cross-sectional study conducted from February 2019 to February 2020, we applied stratified multistage random sampling to investigate residents aged 35 to 75 years in Dancheng county of Zhoukou city and Xincai county of Zhumadian city, both in Central China.ResultsWe enrolled 63,940 participants in this survey. A total of 43.6% (95% confidence interval [CI]: 43.2-44.0) of participants had hypertension. Of these, 49.3% (95% CI: 48.7-49.9) were aware of their diagnosis, 36.5% (95% CI: 35.9-37.1) took antihypertensive medication, and 14.3% (95% CI: 13.9-14.7) had their blood pressure under control. Only 31.4% of hypertensive people receiving antihypertensive treatment had achieved control. The hypertension prevalence was lower in urban areas than in rural areas, with higher rates of awareness, treatment, and control. Among subgroups, rural men had the highest prevalence of hypertension. Prevalence, awareness, and treatment rates all increased with age, except for control rates, which declined in the 65- to 75-year-old group.ConclusionsPeople in Central China have a high hypertension prevalence but low rates of awareness, treatment, and control. Great effort is needed to improve the prevention and management of hypertension in this region.
Project description:BackgroundThe prevalence of childhood overweight and obesity in China has drastically increased 57 times over the past 30 years, and to control birth weight is an effective way to reduce the risk of overweight and obesity across the life course.ObjectiveThis paper aimed to evaluate the association of high birth weight (HBW) with overweight and obesity in Chinese students aged 6-18 years.MethodsAll students with HBW (n=4981) aged 6-18 years were selected from a cross-sectional survey from seven provinces of China, and 4981 other students with normal birth weight (NBW) were randomly sampled with matched gender, age and province. Anthropometric parameters were measured and characteristics were collected by questionnaires. Multiple logistic regression was used to estimate the OR of overweight and obesity with HBW, unadjusted and adjusted for confounding factors.ResultsParticipants with HBW revealed higher body mass index in childhood. The prevalence of overweight and obesity was significantly higher in the HBW group than in the NBW group (overweight 15.3% vs 13.1%, p<0.05; obesity 16.9% vs 10.6%, p<0.05), and the results were similar for overweight in all age groups except age 6-7, age 14-15 and age 16-18. Additionally, HBW was positively associated with overweight (OR=1.230; 95% CI 1.056 to 1.432) and obesity (OR=1.611; 95% CI 1.368 to 1.897) after adjustment for covariates.ConclusionsHBW leads to an increased risk of overweight and obesity in childhood; thus, measures to control birth weight, such as controlling gestational weight gain, should be taken from the earliest beginning of life.Trial registration numberNCT02343588; Post-results.
