Prevalence of hepatitis C virus infection and its correlates in a rural area of southwestern China: a community-based cross-sectional study.

ABSTRACT:

Objectives

Hepatitis C virus (HCV) infection is a major public health problem in southwestern China. Our aim of the study was to assess the prevalence of HCV infection and its correlates in the Yi population of this region.

Methods

A community-based survey was conducted to investigate sociodemographic characteristics and other associated factors for HCV infection in a rural area of southwestern China. Blood samples were collected and tested for antibodies to HCV. Anti-HCV positive samples were further assessed for HCV RNA.

Results

A total of 2558 participants aged ?14 years were included in our analysis. Of them, 2.8% (95%?CI 2.2% to 3.5%) were positive for HCV antibody. Multiple logistic regression analysis revealed that sex (male vs female: adjusted OR (aOR)=3.30, 95% CI 1.80 to 6.07), marital status (unmarried vs married: aOR=0.27, 95% CI 0.09 to 0.80), ever using injection drug (aOR=28.65, 95% CI 15.9 to 51.64) and ever having blood transfusion (aOR=7.64, 95% CI 1.94 to 30.16) were significantly associated with HCV infection (indicated by positive HCV antibody). Stratified analysis by HIV infection found that in HIV-negative individuals, sex (male vs female: aOR=3.84, 95% CI 1.88 to 7.85), ever using injection drug (aOR=22.15, 95% CI 8.45 to 58.04), having multiple sexual partners (aOR=2.57, 95% CI 1.26 to 5.23), and ever having blood transfusion (aOR=16.54, 95% CI 4.44 to 61.58) were significantly associated with HCV infection and in HIV-positive individuals, ever using injection drug (aOR=8.96, 95% CI 3.16 to 25.38) was associated with HCV infection.

Conclusion

The data suggested a higher risk of HCV infection in this area when compared with the rest of China and some unique associated factors. Rapid scale-up of targeted interventions are needed to prevent further transmission and consequent morbidities.

Project description:ObjectivesWe aimed to estimate the prevalence and correlates of QT interval prolongation in rural Uganda.BackgroundMajor electrocardiographic abnormalities, including prolonged QT interval, have been shown to be independently predictive of adverse cardiovascular events among Western populations. Cardiovascular diseases are on the rise in sub-Saharan Africa with poorly characterized context-specific risk factors. An important question is whether ECG screening might have value in cardiovascular disease risk stratification in SSA.MethodsWe conducted a cross-sectional survey in a sample of adults participating in an ongoing whole-population cohort in Mbarara, Uganda, in 2015. Of 1,814 subjects enrolled in the parent whole-population cohort, 856 (47%) participated in the study. Participants completed 12-lead electrocardiography and cardiovascular disease risk factors assessment. We summarized sex-specific, heart rate variation-adjusted QT (QTa) defining prolonged QTa as >460 ms in women and >450 ms in men. We fit linear and logistic regression models to estimate correlates of (continuous) QTa interval length and (dichotomous) prolonged QTa. Models included inverse probability of sampling weights to generate population-level estimates accounting for study nonparticipation.ResultsWe assessed data from 828 participants with electrocardiograms. The weighted population mean age was 38.4 years (95% confidence interval: 36.3-40.4). The weighted population was 50.4% female, 11.5% had elevated blood pressure, and 57.6% had a high-sensitivity C-reactive protein >1 mg/dl. The population mean QTa was 409.1 ms (95% confidence interval: 405.1-413.1), and 10.3% (95% confidence interval: 7.8-13.5) met criteria for prolonged QTa. Women had a higher mean QTa (421.6 ms vs. 396.3 ms; p < 0.001), and a higher proportion of women had a prolonged QTa (14.0% vs. 9.3%; p = 0.122) than did men. In multivariable-adjusted regression models, female sex and hypertension correlated with higher mean QTa and meeting criteria for prolonged QTa, respectively.ConclusionsQT interval prolongation is highly prevalent in rural Uganda and may be more common than in high-income settings. Female sex, age, and high blood pressure correlated with QT interval prolongation. Future work should assess whether genetic predisposition or environmental factors in sub-Saharan African populations contribute to prolonged QT and clarify consequences.

Project description:BackgroundExclusive breastfeeding (EBF) can prevent death and disease among young children. The proportion of EBF is low in Niger. This study aimed to identify the prevalence and correlates of exclusive breastfeeding.MethodsWe conducted a community-based cross-sectional study in urban and rural areas of Niger among mothers of infants under 7 months old. We used a structured questionnaire to investigate breastfeeding practices, sociodemographic factors, and health service use. We used multivariate analysis to explore the correlates of EBF since birth.ResultsThe study involved 234 urban and 283 rural mothers. Colostrum was almost universally given to newborns (98.7% [231/234] urban and 97.9% [277/283] rural) and many mothers started breastfeeding within an hour of giving birth (69.2% [162/234] and 90.5% [256/283]). The proportion of EBF since birth in urban and rural areas was 15.8% (37/234) and 54.4% (154/283), respectively. Among mothers who had ceased EBF, proportion of prelacteal feeding was 85.3% (168/197) in urban areas and 62.0% (80/129) in rural areas, while 93.4% (183/196) and 72.7% (88/121) had stopped EBF within 1 week after birth respectively. The median duration of EBF was 1 week in urban and 2 months in rural areas. In urban areas, EBF was more likely in mothers with infants 3 months old or younger (Adjusted Odds Ratio [AOR] 2.78; 95% Confidence Interval 95% [CI] 1.07, 7.21) and problems with delivery including Caesarean section (AOR 3.60; 95% CI 1.17, 11.01). In rural areas, lower socioeconomic status (AOR 1.89; 95% CI 1.12, 3.18), early initiation of breastfeeding (AOR 4.04; 95% CI 1.50, 10.83) and delivery assisted by a traditional birth attendant (AOR 3.49; 95% CI 1.37, 8.89) were correlated with exclusive breastfeeding.ConclusionsExclusive breastfeeding was uncommon. Most mothers ceased EBF within 1 week after birth. Adequate information about EBF by health professionals around delivery seems to encourage its use. To encourage EBF in Niger, it is important to educate health professionals, including traditional birth attendants, and enable them to discuss the practice with mothers through individual counselling or group education.

Project description:BackgroundUndernutrition among under five children in India is a major public health problem. Despite India's growth in the economy, the child mortality rate due to undernutrition is still high in both urban and rural areas. Studies that focus on urban slums are scarce. Hence the present study was carried out to assess the prevalence and determinants of undernutrition in children under five in Maharashtra, India.MethodsA community-based cross-sectional study was conducted in 16 randomly selected clusters in two districts of Maharashtra state, India. Data were collected through house to house survey by interviewing mothers of under five children. Total 2929 mothers and their 3671 under five children were covered. Multivariate logistic regression analysis was carried out to identify the determinants of child nutritional status seperately in urban and rural areas.ResultsThe mean age of the children was 2.38 years (±SD 1.36) and mean age of mothers was 24.25 years (± SD 6.37). Overall prevalence of stunting among children under five was 45.9%, wasting was 17.1 and 35.4% children were underweight. Prevalence of wasting, stunting and underweight were more seen in an urban slum than a rural area. In the rural areas exclusive breast feeding (p < 0.001) and acute diarrhea (p = 0.001) were associated with wasting, children with birth order 2 or less than 2 were associated with stunting and exclusive breast feeding (p < 0.05) and low maternal education were associated with underweight. Whereas in the urban slums exclusive breast feeding (p < 0.05) was associated with wasting, sex of the child (p < 0.05) and type of family (p < 0.05) were associated with stunting,and low income of the family (p < 0.05) was associated with underweight.ConclusionsFactors like sex of the child, birth order,exclusive breast feeding,economic status of the family, type of family,acute diarrhea and maternal education have influence on nutritional status of the child. Improvement of maternal education will improve the nutritional status of the child. Strategies are needed to improve the economic status of the community.Trial registrationTrial registration number: CTRI/2017/12/010881 ; Registration date:14/12/2017. Retrospectively registered.

Project description:BackgroundIn recent 10 years, with the rapid socioeconomic development and the extensive implementation of children nutrition improvement projects, the previous epidemiological data cannot reflect the actual level of anemia among children in China, especially in rural areas. Therefore, this study analyzed the prevalence, severity and associated factors of anemia among children aged 6-71 months in rural Hunan Province.MethodsA community-based cross-sectional study was conducted. Through multistage stratified cluster sampling, 5229 children aged 6 to 71 months and their caregivers were randomly selected from 72 villages across 24 towns in 12 counties from rural Hunan. The demographic characteristics of children and their caregivers, feeding practice, nutritional status of children, caregivers' anemia-related feeding knowledge, and gestational conditions of mothers were acquired by using a unified questionnaire. Peripheral blood from the left-hand middle fingertip was sampled from each child, and hemoglobin concentration was measured using a HemoCue301 portable hemoglobin analyzer (Sweden). Associated factors analyses involving overall anemia and anemia severities were conducted on multivariate logistic regression models.ResultsThe overall anemia prevalence was 8.8%, and the prevalence of mild, moderate and severe anemia was 6.3, 2.5 and 0.1%, respectively. Children age groups of 6-11 months, 12-23 months and 36-47 months, exclusive breast-feeding within 6 months after birth, and maternal moderate/severe anemia were significantly associated with an increased risk of overall anemia in children. Children age groups of 6-11 months and 12-23 months were significantly associated with an increased risk of mild anemia in children. Children age groups of 6-11 months, 12-23 months and 36-47 months, low caregivers' anemia-related feeding knowledge level, and maternal moderate/severe anemia were significantly associated with an increased risk of moderate/severe anemia in children. Children who underwent regular physical examination were less likely to have moderate/severe anemia. The common protective factor for overall, mild and moderate/severe anemia in children was high family income.ConclusionsThe anemia status of preschool children in rural Hunan Province was a mild public health problem and associated with children age group, feeding practice, regular physical examination, family income, caregivers' anemia-related feeding knowledge level, and maternal moderate/severe anemia.
