BACKGROUND: The aim of this study was to detect possible etiological factors in the origin of isolated congenital cataracts. METHODS: The data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980-2002, contains 111 cases of isolated congenital cataract and 111 matched control pairs without the defect, 37,837 population controls without any defects, and 22,744 malformed controls with other nonocular abnormalities. Exposure data and family history are based on prospective medical records, retrospective maternal information, and information obtained by regional nurses during a home visit with nonrespondent mothers. RESULTS: A positive family history indicated an autosomal-dominant origin in 10% of cases. Rubella infections occurred more frequently in case mothers than in control mothers before vaccination against rubella virus was instituted. A higher prevalence of influenza or common cold during pregnancy was found in the case group (55.9%) than in the population control group (18.5%; adjusted odds ratios [ORs], 5.8; 95% confidence interval (CI), 4.0-8.4) or in the malformed control group (21.7%; adjusted OR, 4.7; 95% CI, 3.2-6.9). The prevalence of acute infectious diseases of the respiratory system during pregnancy was also higher in the case group (26.1%) than in the population control group (9.1%; adjusted OR, 3.8; 95% CI, 2.5-5.8), or the malformed control group (9.3%; adjusted OR, 3.4; 95% CI, 2.3-5.3). The higher risk for isolated congenital cataract in cases of mothers with influenza or common cold and acute infectious diseases of the respiratory system during pregnancy was not found after administration of antifever therapy. CONCLUSIONS: Some isolated congenital cataracts are preventable by rubella vaccination and probably by influenza vaccination in the epidemic period. In addition, our results suggest that using antifever therapy for fever-related respiratory diseases may restrict the teratogenic risk of hyperthermia. 相似文献

Objective:
The prevalence of overweight and obesity among women of reproductive age is increasing. We aimed to determine risk factors and maternal, fetal and childhood consequences of maternal obesity and excessive gestational weight gain.Design and Methods:
The study was embedded in a population‐based prospective cohort study among 6959 mothers and their children. The study was based in Rotterdam, The Netherlands (2001–2005).Results:
Maternal lower educational level, lower household income, multiparity, and FTO risk allel were associated with an increased risk of maternal obesity, whereas maternal European ethnicity, nulliparity, higher total energy intake, and smoking during pregnancy were associated with an increased risk of excessive gestational weight gain (all p‐values <0.05). As compared to normal weight, maternal obesity was associated with increased risks of gestational hypertension (OR 6.31 (95% CI 4.30, 9.26)), preeclampsia (OR (3.61, (95% CI 2.04, 6.39)), gestational diabetes (OR 6.28 (95%CI 3.01, 13.06)), caesarean delivery (OR 1.91 (95% CI 1.46, 2.50)), delivering large size for gestational age infants (OR 2.97 (95% CI 2.16, 4.08)), and childhood obesity (OR 5.02 (95% CI:2.97, 8.45)). Weaker associations of excessive gestational weight gain with maternal, fetal and childhood outcomes were observed, with the strongest effects for first trimester weight gain.Conclusions:
Our study shows that maternal obesity and excessive weight gain during pregnancy are associated with socio‐demographic, lifestyle, and genetic factors and with increased risks of adverse maternal, fetal and childhood outcomes. As compared to prepregnancy overweight and obesity, excessive gestational weight gain has a limited influence on adverse pregnancy outcomes. 相似文献4.
Background
Peripheral artery disease (PAD) is an important global health problem and contributes to notable proportion of morbidity and mortality. This particular manifestation of systemic atherosclerosis is largely under diagnosed and undertreated. For sustainable preventive strategies in a country, it is mandatory to identify country-specific risk factors. We intended to assess the risk factors of PAD among adults aged 40–74 years.Methods
This case control study was conducted in 2012–2013 in Sri Lanka. Seventy-nine cases and 158 controls in the age group of 40–74 years were selected for the study in order to have case to control ratio 1:2. The criterion for selecting cases and control was based on Ankle brachial pressure index (ABPI). Cases were selected from those who had ABPI 0.85 or less (ABPI ≤0.85) in either lower limb. Controls were selected from those ABPI score between 1.18 and 1.28 in both lower limbs. Only newly identified individuals with PAD were selected as cases. Controls were selected from the same geographical location and within the 5 year age group as cases.Results
The history of diabetes mellitus more than 10 years (OR 5.8, 95% CI 2.2–14.2), history of dyslipidemia for more than 10 years (OR 4.9, 95% CI 2.1–16.2), history of hypertension for more than 10 years (OR 3.8, 95% CI 1.8–12.7) and smoking (OR 2.9, 95% CI 1.2–6.9), elevated HsCRP (OR 3.7, 95% CI 1.2–12.0) and hyperhomocysteinemia (OR 3.0, 95% CI 1.1–8.1) were revealed as country specific significant risk factor of PAD.Conclusions
Diabetes mellitus, hypertension, dyslipidemia, smoking as well as elevated homocysteine and HsCRP found as risk factors of PAD. Longer the duration or higher level exposure to these risk factors has increased the risk of PAD. These findings emphasis the need for routine screening of PAD among patients with the identified risk factors.5.

Increasing numbers of aging individuals with chronic co-morbidities travel to regions where falciparum malaria is endemic. Non-communicable diseases are now leading risk factors for death in such countries. Thus, the influence of chronic diseases on the outcome of falciparum malaria is an issue of major importance. Aim of the present study was to assess whether non-communicable diseases increase the risk for severe imported falciparum malaria. A retrospective observational study of all adult cases with imported falciparum malaria hospitalized between 2001 and 2015 in the tertiary care Charité University Hospital, Berlin, was performed. A total of 536 adult patients (median age 37 years; 31.3% female) were enrolled. Of these, 329 (61.4%) originated from endemic countries, 207 patients (38.6%) from non-endemic regions. Criteria for severe malaria were fulfilled in 68 (12.7%) cases. With older age, lack of previous malaria episodes, being a tourist, and delayed presentation, well-characterized risk factors were associated with severe malaria in univariate analysis. After adjustment for these potential confounders hypertension (adjusted odds ratio aOR, 3.06 95% confidence interval, CI 1.34–7.02), cardiovascular diseases (aOR, 8.20 95% CI 2.30–29.22), and dyslipidaemia (aOR, 6.08 95% CI 1.13–32.88) were individual diseases associated with severe disease in multivariable logistic regression. Hypertension proved an independent risk factor among individuals of endemic (aOR, 4.83, 95% CI 1.44–16.22) as well as of non-endemic origin (aOR, 3.60 95% CI 1.05–12.35). In imported falciparum malaria hypertension and its related diseases are risk factors for severe disease. 相似文献

The association between T174M polymorphism of angiotensinogen gene and essential hypertension risk remains controversial. We herein performed a meta-analysis to achieve a reliable estimation of their relationship. All the studies published up to May 2013 on the association between T174M polymorphism and essential hypertension risk were identified by searching the electronic repositories PubMed, MEDLINE and EMBASE, Springer, Elsevier Science Direct, Cochrane Library and Google Scholar. Data were extracted and pooled odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated. Ultimately, nine eligible studies, including 2188 essential hypertension cases and 2459 controls, were enrolled in this meta-analysis. No significant associations were found under the overall ORs for M-allele comparison (M vs. T, pooled OR 0.92, 95% CI 0.62–1.37), MM vs. TT (pooled OR 0.86, 95% CI 0.29–2.51), TM vs. TT n (pooled OR 0.91, 95% CI 0.63–1.32), recessive model (MM vs. TT+TM, pooled OR 0.89, 95% CI 0.35–2.30), dominant model (MM+TM vs. TT, pooled OR 0.91, 95% CI 0.60–1.38) between T174M polymorphism and risk for essential hypertension. This meta-analysis suggested that the T174M polymorphism of the angiotensinogen gene might not be associated with the susceptibility of essential hypertension in Asian or European populations. 相似文献

BackgroundThe childhood peak of brain tumors suggests that early-life exposures might have a role in their etiology. Hence, we examined in the Greek National Registry for Childhood Hematological Malignancies and Solid tumors (NARECHEM-ST) whether perinatal and early-life risk factors influence the risk of childhood brain tumors.MethodsIn a nationwide case-control study, we included 203 cases (0–14 years) with a diagnosis of brain tumor in NARECHEM-ST (2010–2016) and 406 age-, sex-, and center-matched hospital controls. Information was collected via interviews with the guardians and we analyzed the variables of interest in multivariable conditional logistic regression models.ResultsInstrument-assisted delivery was associated with higher (OR: 7.82, 95%CI: 2.18–28.03), whereas caesarean delivery with lower (OR: 0.67, 95%CI: 0.45-0.99) risk of childhood brain tumors, as compared to spontaneous vaginal delivery. Maternal alcohol consumption during pregnancy (OR: 2.35, 95%CI: 1.45–3.81) and history of living in a farm (OR: 4.98, 2.40–10.32) increased the odds of childhood brain tumors. Conversely, higher birth order was associated with lower risk (OR for 2nd vs. 1st child: 0.60, 95%CI: 0.40-0.89 and OR for 3rd vs. 1st: 0.34, 95%CI: 0.18-0.63). Birth weight, gestational age, parental age, history of infertility, smoking during pregnancy, allergic diseases, and maternal diseases during pregnancy showed no significant associations.ConclusionsPerinatal and early-life risk factors, and specifically indicators of brain trauma, exposure to toxic agents and immune system maturation, might be involved in the pathogenesis of childhood brain tumors. Larger studies should aim to replicate our findings and examine associations with tumor subtypes. 相似文献

The Cytochrome P-450 1A1 (CYP1A1) gene has been implicated in the etiology of hepatocellular carcinoma (HCC). However, the results have been inconsistent. In this study, a meta-analysis was performed to clarify the associations of polymorphisms in CYP1A1 gene with HCC risk. Published literature from PubMed, Embase, CNKI and Wanfang Data were retrieved. Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using fixed- or random-effects model. Eight studies (1,752 cases and 2,279 controls) for Ile-Val polymorphism and eight studies (933 cases and 1,449 controls) for MspI polymorphism were identified. The results showed that there was no statistically significant association between the Ile-Val polymorphism and HCC risk under all genetic models (co-dominant model: Val/Val vs. Ile/Ile: OR = 1.62, 95% CI 0.96-2.72 and Ile/Val vs. Ile/Ile: OR = 1.15, 95% CI 0.87-1.52; dominant model: OR = 1.25, 95% CI 0.92-1.70; recessive model: OR = 1.48, 95% CI 0.99-2.21). The MspI polymorphism was also not associated with HCC risk (co-dominant model: m2m2 vs. m1m1: OR = 1.09, 95% CI 0.83-1.42 and m1m2 vs. m1m1: OR = 1.30, 95% CI 1.05-1.61; dominant model: OR = 1.20, 95% CI 0.99–1.45; recessive model: OR = 0.94, 95% CI 0.74-1.18). However, the significant associations were found between both the Ile–Val and MspI polymorphisms and HCC risk among the cigarette smoking subjects (Ile-Val: OR = 1.40, 95% CI 1.06-1.85; MspI: OR = 2.65, 95% CI 1.47-4.77). The present meta-analysis indicated that the MspI and Ile-Val polymorphisms of CYP1A1 may play important roles in increasing susceptibility to smoking-related HCC. 相似文献

Hepatocellular carcinoma (HCC) is a common malignant tumor and the leading cause of cancer-related death worldwide. The protein encoded by patatin-like phospholipase domain-containing protein 3 (PNPLA3) plays important roles in liver fatty metabolism. Recent studies have indicated associations of PNPLA3 rs738409 with various liver diseases, including HCC. This meta-analysis was performed to investigate and update the association between rs738409 polymorphism and the risk of HCC, and to test the association between rs738409 and HCC specifically in patients within chronic hepatitis B and/or C infection, alcoholic liver disease, or other diseases. Studies were searched from the literature database up to March 31, 2016. The meta-analysis was conducted based on statement of preferred reporting items for systematic reviews and meta-analyses. Pooled odds ratios (OR) and 95 % confidence intervals (CI) were estimated the strength of associations between rs738409 polymorphism and HCC risk. Fifteen published studies, consisting of 2264 HCC patients (case) and 5802 without HCC individuals (control), were included in the present study. Meta-analysis revealed that rs738409 polymorphism contributed to HCC risk under the allelic effect model (C vs. G: OR 1.73; 95 % CI 1.53–1.96), the dominant effect model (CC vs. CG+GG: OR 1.61; 95 % CI 1.44–1.81), and the recessive effect model (CC+CG vs. GG: OR 2.66; 95 % CI 2.28–3.11). Furthermore, the effect of rs738409 G allele on liver oncogenesis was higher in alcoholic liver disease (OR 2.55), compared to chronic hepatitis C/B (OR 1.32) and other diseases (OR 2.27). The results suggested that rs738409 polymorphism was significantly associated with HCC risk and it could be used as one risk factor for HCC. 相似文献

Domestic spousal violence against women in developing countries like India, is now beginning to be recognized as a widespread health problem impeding development. This study aimed to explore the risk and protective factors for lifetime spousal physical violence. A cross-sectional household survey was carried out in rural, urban and urban-slum areas across seven sites in India, among women aged 15-49 years, living with a child less than 18 years of age. The sample was selected using the probability proportionate to size method. Trained field workers administered a structured questionnaire to elicit information on spousal physical violence. The main hypothesized variables were social support, witnessed father beating mother and experience of harsh physical violence during childhood, alcohol abuse by spouse and socioeconomic variables. The outcome variables included three physical violence behaviours of hit, kick and beat. Odds ratios were calculated for risk and protective factors of violence using logistic regression. Of 9938 women surveyed, 26% reported experiencing spousal physical violence during the lifetime of their marriage. Adjusted odds ratios calculated using multiple logistic regression analysis suggest that women whose husbands regularly consumed alcohol (OR 5.6; 95% CI 4.7-6.6); who experienced dowry harassment (OR 3.2; 95% CI 2.7-3.8); had reported experiencing harsh physical punishment during childhood (OR 1.6; 95% CI 1.4-1.8) and had witnessed their fathers beat their mothers (OR 1.9; 95% CI 1.6-2.1), were at increased risk of spousal physical violence (beat, hit and kick). Higher socioeconomic status and good social support acted as protective buffers against spousal physical violence. The findings provide compelling evidence of the potential risk factors for spousal physical violence, which in turn could help in planning interventions. 相似文献

Allele and genotype distributions of the T3111C polymorphism in 3'-untranslated region of the CLOCKgene were examined in the groups of Russian patients with essential arterial hypertension (EAH) and coronary artery disease (CAD), and in control group of Russia residents of the Republic of Karelia. The genotype frequency distributions of the polymorphism examined in the EAH and CAD patients were statistically significantly different from that in the individuals without clinical signs of these diseases. The CC genotype frequency in EAH and CAD males was higher, and in the corresponding females it was lower than in males and females from the control group. Male CC carriers were characterized by a possible increased risk of EAH: OR (95% CI) = 1.42 (0.56; 3.58). Moreover, the presence of the CC genotype in males could increase the risk of CAD: OR (95% CI) = 1.58 (0.63; 3.93). 相似文献

The objective of this study was to analyse the association between socioeconomic indicators and cardiovascular disease risk factors in adult residents of Rio de Janeiro city, Brazil. Data were obtained by direct interview and physical examination in a population-based cross-sectional study in the city of Rio de Janeiro, 1995-96. Subjects were selected by two-stage random sampling and information was collected on socioeconomic, anthropometric and demographic characteristics, as well as on existing risk factors for cardiovascular disease. An index to express the risk of cardiovascular disease (CVD) was built, based on the presence of two or more of the following risk factors: overweight (measured by the body mass index, BMI), fat location (measured by the waist-hip ratio index, WHR), smoking, hypertension, sedentary lifestyle and alcohol consumption. The association between this risk index and the socioeconomic variables level of schooling, per capita income and residence location (slum vs non-slum) was evaluated through logistic regression models that controlled for the age of the subjects. Two separate models were built, according to the gender of the subjects. Complete data were collected for 1413 males and 1866 females over the age of 20 years (82% of the intended sample). In the studied population, a considerable prevalence of risk for CVD was found: 42.2% among males and 65.4% among females. For males, the socioeconomic and demographic indicators retained in the logistic model were age (OR 1.01, 95% CI 1.00-1.01), level of schooling (1.77, 95% CI 1.39-2.26) and per capita income (OR 0.77, 95% CI 0.61-0.97). For females, the indicators retained were age (OR 1.02, 95% CI 1.01-1.02) and level of schooling (OR 2.26, 95% CI 1.84-2.77). The findings indicate that cardiovascular disease risk is already an alarming problem in the urban populations of developing countries, and that educational level is the most important socioeconomic factor associated with its presence. 相似文献

Ischaemic stroke is a multifactorial disease. Genetic polymorphisms involved in lipid, inflammatory and thrombotic metabolisms play an important role in the development of ischaemic stroke. The present study aimed to assess the relationship between T1131C APOA5 and SG13S114 ALOX5AP polymorphisms and the risk of ischemic stroke in 175 cases and 201 controls. Genotyping was performed by high resolution melting and polymerase chain reaction restriction fragment length polymorphism methods. In the case of T-1131C APOA5, a modest risk of ischaemic stroke was noticed with CC (OR: 2.86; 95% CI = 1.24–6.58; Pc = 0.039) and C allele (OR: 1.54; 95% CI = 1.01–2.33; Pc = 0.014). For SG13S114ALOX5AP, a significant association was observed among subjects with TT (OR: 2.57; 95% CI =1.49–4.83; Pc = 0.009) and T allele (OR: 1.59; 95% CI = 1.16–2.19; Pc = 0.008). According to the risk factors of ischaemic stroke, a positive correlation was observed only between SG13S114 variant of ALOX5AP gene and hypertension (Pc = 0.026). Despite lower sample size, T-1131C APOA5 and SG13S114 variants could be considered an independent genetic risk factor of ischaemic stroke in Moroccan population. 相似文献

Studies have suggested an increase in maternal morbidity and mortality due to cardiovascular diseases in women with a prior low-birth-weight (LBW, <2,500 grams) delivery. This study evaluated blood pressure and hypertension in women who reported a prior preterm or small-for-gestational-age (SGA) LBW delivery in the National Health and Nutrition Examination Survey 1999–2006 (n = 6,307). This study also aimed to explore if race/ethnicity, menopause status, and years since last pregnancy modified the above associations. A total of 3,239 white, 1,350 black, and 1,718 Hispanics were assessed. Linear regression models were used to evaluate blood pressure by birth characteristics (preterm-LBW, SGA-LBW, and birthweight ≥2,500). Logistic regression models estimated the odds ratios (OR) of hypertension among women who reported a preterm-LBW or SGA-LBW delivery compared with women who reported an infant with birthweight ≥2,500 at delivery. Overall, there was a positive association between a preterm-LBW delivery and hypertension (adjusted OR = 1.39, 95% confidence interval (CI) 1.02–1.90). Prior SGA-LBW also increased the odds of hypertension, but the estimate did not reach statistical significance (adjusted OR = 1.21, 95% CI 0.76–1.92). Race/ethnicity modified the above associations. Only black women had increased risk of hypertension following SGA-LBW delivery (adjusted OR = 2.09, 95% CI 1.12–3.90). Black women were at marginally increased risk of hypertension after delivery of a preterm-LBW (adjusted OR = 1.49, 95% CI 0.93–2.38). Whites and Hispanics had increased, but not statistically significant, risk of hypertension after a preterm-LBW (whites: adjusted OR = 1.39, 95% CI 0.92–2.10; Hispanics: adjusted OR = 1.22, 95% CI 0.62–2.38). Stratified analysis indicated that the associations were stronger among women who were premenopausal and whose last pregnancy were more recent. The current study suggests that in a representative United States population, women with a history of preterm- or SGA-LBW deliveries have increased odds of hypertension and this risk appears to be higher for black women and younger women. 相似文献

Purpose
We aim to systematically summarize the available epidemiological evidence to identify the impact of environmental tobacco smoke on health.Methods
A systematic literature search of PubMed, Embase, Web of Science, and Scopus for meta-analyses was conducted through January 2015. We included systematic reviews that investigated the association between passive smoking and certain diseases. Quantitative outcomes of association between passive smoking and the risk of certain diseases were summarized.Results
Sixteen meta-analyses covering 130 cohort studies, 159 case-control studies, and 161 cross-sectional studies and involving 25 diseases or health problems were reviewed. Passive smoking appears not to be significantly associated with eight diseases or health problems, but significantly elevates the risk for eleven specific diseases or health problems, including invasive meningococcal disease in children (OR 2.18; 95% CI 1.63–2.92), cervical cancer (OR 1.73; 95% CI 1.35–2.21), Neisseria meningitidis carriage (OR 1.68; 95% CI 1.19–2.36), Streptococcus pneumoniae carriage (OR 1.66; 95% CI 1.33–2.07), lower respiratory infections in infancy (OR 1.42; 95% CI 1.33–1.51), food allergy (OR 1.43; 95% CI 1.12–1.83), and so on.Conclusions
Our overview of systematic reviews of observational epidemiological evidence suggests that passive smoking is significantly associated with an increasing risk of many diseases or health problems, especially diseases in children and cancers. 相似文献18.

ABSTRACT: BACKGROUND: Lactation has beneficial short term effects on maternal metabolic health, but the long term effects are less well known. METHODS: We studied the association between lifetime duration of lactation and cardiovascular risk factors in mothers later in life among 21,368 parous women aged 20 to 85 years attending the second Nord-Trondelag Health Study (HUNT2) in 1995-1997, Norway, a cross-sectional population-based study. General linear modelling was used to calculate mean values of known cardiovascular risk factor levels in five categories of lifetime duration of lactation. Logistic regression was conducted to estimate odds ratios of hypertension, obesity and diabetes. RESULTS: Among women aged 50 years or younger, lifetime duration of lactation was significantly and inversely associated with body mass index (P-trend, < 0.001), waist circumference (P-trend, < 0.001), systolic and diastolic blood pressure (both P-trends, < 0.001), and serum levels of triglycerides, total cholesterol and low density lipoprotein cholesterol (all P-trends, < 0.001) after adjustment for covariates. Parous women aged 50 years or younger who had never lactated had higher prevalence of hypertension, obesity and diabetes. In this age group, compared to women who had lactated for 24 months or more, parous women who had never lactated had an OR for hypertension of 1.88 (95% CI 1.41, 2.51), an OR for obesity of 3.37 (95% CI 2.51, 4.51) and an OR for diabetes of 5.87 (95% CI 2.25, 15.3). Among women older than 50 years there were no clear associations. CONCLUSION: Lifetime duration of lactation was associated with long term reduced cardiovascular risk levels in mothers aged 50 years or younger. 相似文献

Background
Low birth weight (LBW) is associated with an increased risk of mortality, adverse metabolic conditions, and long-term chronic morbidities. The relationship between LWB and short maternal stature coupled with nutritional status was investigated in poor communities.Methods/Principal Findings
A cross-sectional population-based study involving 2226 mother-child pairs was conducted during the period 2009-2010 in shantytowns of Maceió, Alagoas, Brazil. Associations between LBW and maternal sociodemographics, stature and nutritional status were investigated. The outcome variable was birth weight (< 2500g and ≥ 2500g). The independent variables were the age, income, educational background, stature and nutritional status (eutrophic, underweight, overweight and obese) of the mother. The frequency of LBW was 10%. Short-statured mothers (1st quartile of stature ≤ 152cm) showed a tendency of increased risk of LBW children compared to mothers in the 4th quartile of stature (>160.4cm) (OR: 1.42, 95% CI: 0.96 - 1.09, p = 0.078). Children from short-statured mothers weighed an average of 125g less than those from taller mothers (3.18±0.56kg vs. 3.30±0.58kg, respectively p = 0.002). Multivariate analyses showed that short stature, age < 20y (OR: 3.05, 95% CI:1.44 - 6.47) or were underweight (OR: 2.26, 95% CI:0.92 - 5.95) increased the risk of LBW, while overweight (OR: 0.38, 95% CI:0.16 - 0.95) and obesity (OR: 0.39, 95% CI:0.11 - 1.31) had lower risk for LBW. In taller mothers, lower income and underweight were associated with LBW (OR: 1.88, 95% CI: 1.07 - 3.29 and 2.85, 95% CI:1.09 - 7.47, respectively), and obese mothers showed a trend of increased risk of LBW (OR: 1.66, 95% CI:0.84 - 3.25).Conclusions/Significance
Overweight was found to have a protective effect in short-statured mothers, indicating that a surplus of energy may diminish the risk of LBW. Short-statured younger mothers, but not taller ones, showed higher risk of LBW. The mother being underweight, regardless of stature, was associated with LBW. 相似文献20.

BACKGROUND: Vitamin deficiencies induce oral clefts in animal experiments, but the role of specific nutrients in human oral clefts is uncertain. METHODS: Associations between maternal vitamin B-6 and folate status and risk of nonsyndromic cleft lip, with or without cleft palate (CL/P), were examined in case-control studies at two sites in the Philippines--Negros Occidental and Davao. Cases were mothers of affected children and control mothers were those who had no children with oral clefts. RESULTS: The risk of having a CL/P-affected child increased with increasing tertile of vitamin B-6 deficiency in both Negros Occidental and Davao (odds ratios [ORs] and 95% confidence intervals [CIs] for sites combined = 1.0 [reference], OR, 2.94; 95% CI, 1.51-5.73; OR, 4.98; 95% CI, 2.56-9.67). Poor B-6 status had a stronger association with CL/P among mothers with lower versus higher plasma folate levels. Increasing tertiles of plasma folate were marginally associated with an increased risk of clefts in both sites combined (1.0 [reference]; OR, 1.58; 95% CI, 0.93-2.68; OR, 1.59; 95% CI, 0.94-2.70). Increasing tertiles of erythrocyte folate were associated with a decreased risk of CL/P in Negros Occidental (1.0 [reference]; OR, 0.34; 95% CI, 0.13-0.90; OR, 0.46; 95% CI, 0.20-1.09) and an increased risk in Davao (1.0 [reference]; OR, 1.23; 95% CI, 0.54-2.81; OR, 4.85; 95% CI, 2.24-10.50). The inconsistent associations between folate status and CL/P risk appeared to be a result of statistical interaction between folate, vitamin B-6, and case-control status that produced different results in study areas of higher versus lower prevalence of vitamin B-6 deficiency. CONCLUSIONS: Poor maternal vitamin B-6 status was consistently associated with an increased risk of CL/P at two sites in the Philippines. Folate-CL/P associations were inconsistent and may be related to the vitamin B-6 status or other characteristics of the populations under study. 相似文献
