Prevalence and risk factors of hypovitaminosis D in pregnant Spanish women.

ABSTRACT: The hypovitaminosis D epidemic is a global health problem. Our aim was to assess the prevalence and potential risk factors of hypovitaminosis D among pregnant women on the eastern Mediterranean coast. Cross-sectional analysis involved 793 healthy pregnant women (35.3?±?5.0 years) participating in ECLIPSES, a multicenter randomized trial. Socio-demographic, obstetric, anthropometric, lifestyle, dietary variables and blood draw was collected in the first trimester. Vitamin D deficiency was identified in 50.2% and insufficiency in 30.3% of pregnant women. The mean vitamin D level in the overall sample was 33.9 nmol/L (SD, 17.0). Multivariable logistic regression analysis applying AIC-based backward selection identified excess weight during the 1st trimester (BMI???25 kg/m2) (OR?=?1.950, 95% CI?=?1.409, 2.699), Arab ethnic group/dark skin colour (OR?=?4.005, 95% CI?=?2.488, 6.447), winter/spring (OR?=?4.319, 95% CI?=?3.112, 5.994), and consumption of milk (OR?=?0.754, 95% CI?=?0.572, 0.993) and yogurt (OR?=?0.635, 95% CI?=?0.436, 0.922) as independent risk factors for vitamin D deficiency. All of these factors (except yogurt consumption) and physical activity were independently associated with vitamin D deficiency/insufficiency risk in the final multivariable model (all p?

Project description:BackgroundThe oral health status of pregnant women in low-resource communities such as Nepal has not been well characterized. This sub-population is also of specific interest given associations between poor oral health and adverse pregnancy outcomes previously documented in other settings. We explored relationships between gingivitis and risk factors among pregnant women in rural Nepal.MethodsThe design was a community-based, cross-sectional study in a sub-area of Sarlahi District, Nepal. Pregnant women < 26 weeks gestation underwent clinical periodontal exams conducted by community-based oral health workers. Exams included a full mouth assessment measuring bleeding on probing (BOP), probing depth (PD) (six sites per tooth), and gingival recession, the distance from the cemento-enamel junction to the free gingival margin (two direct sites per tooth). Data on participant risk factors were collected through household surveys, including demographic characteristics, oral health behaviors, care seeking, and health attitudes. Multivariable logistic regression modeling was used to assess relationships between gingivitis and risk factors.ResultsWe enrolled 1452 participants, of which 40% (n = 582) had signs of clinical gingivitis and 60% (n = 870) clinical health. Average participant age was 23. Most participants (88%) had never received oral health care. Participants averaged 10% of sites with BOP with most (79%) having ≥1 site with BOP. Nine percent of participants had ≥1 site with PD ≥4 mm, although very few participants (0.7%) had sites with PD ≥5 mm. Few participants (13%) had any recession (≥1 mm). In the final adjusted model, odds of gingivitis increased by 3% for each year of age (aOR 1.03, 95% CI 1.00, 1.06) and were higher for women of short maternal stature (< 150 cm) (aOR 1.43, 95% CI: 1.14, 1.79) and among women reporting cost to be a barrier to seeking dental care (aOR 2.13, 95% CI: 1.09, 4.15).ConclusionsGingivitis was common and associated with age, maternal stature, self-reported high cost of dental care, and other risk factors among pregnant women in rural Nepal.Trial registrationClinicalTrials.gov Identifier: NCT01177111 (Nepal Oil Massage Study) and NCT02788786 (Pilot Trial).

Project description:Vitamin A plays an important role in the periods of rapid cellular growth and differentiation, especially during pregnancy, which is supplied by the mother to the fetus. The aim of this study is to assess the prevalence and potential influence factors of prenatal VAD of Chinese pregnant women.China National Nutrition and Health Survey 2010-2013(CHNNS2010-2013) is a nationally representative cross-sectional study. It involved the random selection of 150 districts (urban) or counties (rural). Each site randomly selected 30 pregnant women. Because volume of blood and incomplete data was taken into consideration,the final sample was formed by 1209 participants. Serum retinol concentrations were measured by high performance liquid chromatography. Characteristics of the pregnant women were collected by a questionnaire. Comparing retinol level across categories of independent variables was tested by the Mann-Whitney U test. Logistic and linear regression analyses were used to identify influence factors of Chinese pregnant women.The mean serum retinol level of the pregnant women was 1.63 μmol/L (95 % CI 1.60-1.67) and 64[5.3 % (95 % CI 4.03-6.56)] had VAD. The odds of VAD were significantly higher among the pregnant women in the poor rural areas and without college or university education and low- income. Pregnant women in the second and third trimester had 2.40 (95 % CI 1.05-5.46) and 2.82 (95 % CI 1.34-5.93) times increased odds of VAD compared with those in the first trimester respectively. Pregnant women of drinker had 3.10(1.65-5.81) times increased odds of VAD compared with those no drinker. Pregnant smokers had 5.68 (95 % CI 2.23-14.49) times higher odds of VAD compared with pregnant with non-smoker without passive smoking.VAD is of mild public-health issue in Chinese pregnant women. Such as : in the poor rural areas and without received college or university education and low- income and advanced gestational age and unhealthy lifestyles of pregnant women such as smoking and drinking. These were pertinent influence factors of VAD.

Project description:BACKGROUND: Malaria during pregnancy remains a serious public health problem. The aim of this study was to determine the prevalence and possible risk factors for malaria in pregnant women attending antenatal clinic at two primary health facilities in Bobo-Dioulasso. METHODS: We conducted a cross sectional study from September to December 2010 in two primary health facilities located in the periurban area of Bobo-Dioulasso. Pregnant women attending antenatal clinic (ANC) were included in the study after signing informed consent. For each participant, the social-demographic profile, malaria and obstetric histories were investigated through a questionnaire. Peripheral blood was collected and thick and thin blood smears were prepared to check Plasmodium falciparum parasitaemia. Hemoglobin concentration was measured. The associations between age, parity, gestational age, schooling, number of ANC visits, use of IPTp-SP, use of insecticide-treated nets (ITN) and anemia with the occurrence of P. falciparum malaria infection during pregnancy were analyzed through logistic regression. RESULTS: During the period of study, 105 (18.1%) out of 579 pregnant women were infected by P. falciparum. The hemoglobin concentration mean was 10.5?±?1.7/dL and was significantly lower in pregnant women with malaria infection (9.8 g/dL ±1.6) than in those who had no malaria infection (10.6 g/dL ±1.7) (P?<?0.001). Multivariate analysis indicated that, education (AOR 1.9, 95% CI?=?[1.2-3.2]), parity [primigravidae (AOR 5.0, 95% CI?=?[2.5-9.8]) and secundigravidae (AOR 2.1, 95% CI?=?[1.2-3.8])], and anaemia (AOR 2.1, 95% CI?=?[1.3-3.5]) were significantly associated with P. falciparum malaria infection. The use of IPTp-SP was not associated with P. falciparum malaria infection. CONCLUSIONS: P. falciparum malaria infection is common in pregnant women attending antenatal clinic and anaemia is an important complication. The results show that the use of IPTp-SP does not reduce the risk of malaria incidence during pregnancy.

Project description:ObjectiveKnowledge regarding the prevalence and risk factors of hepatitis C virus (HCV) infection among pregnant women can give clue to health care providers regarding the appropriate management of HCV infection. Therefore, this study was conducted to determine the prevalence, genotypic pattern, and risk factors of HCV infection among pregnant women in the northern shores of the Persian Gulf, south of Iran.MethodsFrom January 2018 to June 2019, serum samples were obtained from 1425 pregnant women, ages ranging from 14 to 46 years (28.1 ± 5.99). Serum samples were tested for detection of anti-HCV antibodies using an enzyme-linked immunosorbent assay (ELISA) (HCV Ab ELISA kit, Dia.Pro, Milan, Italy). Following the extraction of nucleic acid, the molecular evaluation of HCV infection was performed by seminested reverse transcriptase-polymerase chain reaction assay (RT-PCR), targeting the 5' untranslated region (5'UTR) and core of HCV genome and sequencing.ResultsOf the 1425 pregnant women, 19 women (1.33%, 95% CI: 0.85%-2.07%) were positive for anti-HCV antibodies. The majority of HCV-seropositive women were in the third trimester of pregnancy, educated, and had a history of blood transfusion, abortion, surgery, or dentistry. Moreover, Arab and Fars pregnant women and those aged >39 years had the highest rate of HCV seroprevalence. Nevertheless, none of these variables were significantly associated with HCV seropositivity. In contrast, HCV seropositivity was associated with place of residency, so that residents of Khormuj city had significantly higher HCV seroprevalence compared to the residents of other cities (OR: 7.05; 95% CI: 1.75-28.39; P = 0.006). According to the molecular evaluation, 9 of the 19 HCV-seropositive pregnant women (47.37%) had HCV viremia with genotype 3a.ConclusionThis study reports the HCV prevalence of 1.33% for anti-HCV antibodies and 0.63% for HCV RNA among pregnant women in the south of Iran. Considering the asymptomatic nature of chronic HCV infection and the fact that vertical transmission is possible in women with detectable viremia, therefore, screening of women before pregnancy is recommended to reduce the risk of HCV infection and its complications during pregnancy.
