Years Of School Education Research Articles

Games and Sports Preferences of Children.

The Turkish educational system entered into the process of a compulsory 12 years of school education starting from the 2012-2013 academic year. In this process, the name of the physical education lesson has been changed to “games and physical activities” in the primary schools that offer education for 4 years. The aim of the present study is to determine the game and sports preferences of the children who received education in the 2011-2012 academic year between the 4th and the 8thgrades. The questionnaire of Celli, “Games and Sports” was translated into Turkish and was used as data collecting tool in the study. The population of the study consisted of 716 students. The subjects of the study included the preferred sports and games in open areas in winter and in summer, the preferred sports in closed areas, favorite games at home and favorite sports and games overall. The differences between playing games or sports in summer and in winter; playing games or sports in open and closed areas; playing individual games or sports or in a team; liking or not liking rough-and-tumble play were determined. The research results were supported with discussion. Key words: Sports preference, game preference, education, Turkey, sport branches.

Central obesity in Yemeni children: A population based cross-sectional study

To establish percentile curves and to explore prevalence and correlates of central obesity among Yemeni children in a population based cross-sectional study. A representative sample of 3114 Yemeni children (1564 boys, 1550 girls) aged 6-19 years participating in the HYpertension and Diabetes in Yemen study was studied. Data collection was conducted at home by survey teams composed of two investigators of both genders. Study questionnaire included questions about demographics, lifestyle, and medical history. Anthropometric measurements included body weight, height, waist circumference (WC) and hip circumferences. Waist to hip ratio (WHR) and waist-to-height ratio (WHtR) were then calculated. Age and gender specific smoothed percentiles of WC, WHR, and WHtR were obtained using lambda-mu-sigma parameters (LMS method). The independent predictors of central obesity defined as (1) WC percentile ≥ 90(th); (2) WHtR ≥ 0.5; or (3) WC percentile ≥ 90(th) and WHtR ≥ 0.5, were identified at multivariate logistic regression analysis adjusted for age, gender, urban/rural location, years of school education, sedentary/active life-style. Percentile curves for WC, WHR and WHtR are presented. Average WC increased with age for both genders. Boys had a higher WC than girls until early adolescence and thereafter girls had higher values than boys. WHR decreased both in boys and girls until early adolescence. Thereafter while in boys it plateaued in girls it continued to decrease. Mean WHtR decreased until early adolescence with no gender related differences and thereafter increased more in girls than in boys towards adult age. Prevalence of central obesity largely varied according to the definition used which was 10.9% for WC ≥ 90(th) percentile, 18.3% for WHtR ≥ 0.5, and 8.6% when fulfilling both criteria. At adjusted logistic regression WC ≥ 90(th) percentiles and WHtR ≥ 0.5 were less prevalent in rural than in urban areas (OR = 0.52, 95%CI: 0.41-0.67 and 0.66, 0.54-0.79 respectively), being more prevalent in children with sedentary lifestyle rather than an active one (1.52, 95%CI: 1.17-1.98 and 1.42, 95%CI: 1.14-1.75, respectively). Yemeni children central obesity indices percentile curves are presented. Central obesity prevalence varied according to the definition used and was more prevalent in urban sedentary subjects.

Efficacy of a long-term secondary prevention programme following inpatient cardiovascular rehabilitation on risk and health-related quality of life in a low-education cohort: a randomized controlled study

The aim of this study was to evaluate the efficacy of a long-term secondary prevention programme following inpatient cardiovascular rehabilitation on cardiovascular risk and health-related quality of life in a cohort of middle-aged (≤58 years) coronary artery disease (CAD) patients of low educational level compared to usual care. The study included 600 patients with CAD, with 271 in the intervention group (IG) and 329 in the control group (CG). The average age was nearly 50 years in both groups, nearly 90% were male, and 77% had less than 10 years of school education. No significant differences existed between the groups at baseline. Both groups had a 3-week comprehensive cardiovascular inpatient rehabilitation programme at the beginning, the intervention consisted of one further rehabilitation session in hospital after 6 months and regular telephone reminders over a period of 36 months. Analyses were conducted on an intention-to-treat basis. To evaluate the individual risk level, we used the PROCAM score and intima-media thickness (IMT) was measured at the common carotid artery on both sides following international standards. Health-related quality of life was assessed with the EUROQOL and HADS. Patients in the IG showed better 3-year risk profile outcomes. The PROCAM score increased by 3.0 (IG) and by 3.7 (CG) from the beginning to after 3 years (p > 0.05 intention-to-treat). The average IMT increased by 0.04 mm in the CG and was reduced by 0.03 mm in the IG (p = 0.014 for the difference). The IG had a significant improvement in health-related quality of life. Mortality, myocardial infarction, and stroke were not different although 'other cardiac events' (cardiac surgery or intervention) were significantly lower in the IG than the CG patients (p < 0.05). This long-term secondary prevention programme with inpatient rehabilitation at the beginning and telephone reminder for a 3-year period was successful. There were significant differences in health-related quality of life between the IG and CG, despite the relatively positive outcomes in the CG. In this low-education (predominantly male), middle-aged cohort, the positive impact on cardiovascular risk was pronounced in the high-risk subgroup (PROCAM 10-year risk 10-40%).

The Language Detective: A Course for Young Linguists

AbstractThis article reports on a residential course, held at the Villiers Park Educational Trust centre in Foxton, Cambridgeshire, which introduces linguistics to students who are in their final two years of school education. Both students and tutors find the course challenging and fun. Students find the experience of developing their own linguistic investigations hugely rewarding. This is clearly indicated in feedback questionnaires and informal discussion at the end of the course. Feedback regularly shows over 95% of responses in the most positive (‘excellent’) category. Tutors find out more about their subject and about the interests and abilities of students at this level. This is, of course, interesting to any teacher for its own sake. We also have a particular interest in developing activities which make connections between linguistics and language study at school and in higher education.

SP3-76 Incidence and persistence of obesity in Brazilian adults from body mass index at end of adolescence

Cognitive impairment using education-based cutoff points for CMMSE scores in elderly Chinese people of agricultural and rural Shanghai China

To evaluate cognitive impairment (CI) in rural China using the Chinese version of the Mini-Mental Status Examination (CMMSE) and compare the prevalence of CI using two different cutoff points. A population-based survey was conducted of 2809 people aged 60 years and above in a community of two towns (Huaxin and Xujing) in the Qingpu district, located in the western suburb of Shanghai. Face-to-face interviews were carried out to collect relevant information with questionnaires. The Chinese version of the Mini-Mental State Examination with either a 23/24 cutoff point or a cutoff point varying according to education level (AEL) was used to screen subjects for CI. Among these subjects, the mean age was 70.6 years (SD = 6.6) and ranged from 60 to 92 years and included 1010 (36.0%) men and 1799 (64.0%) women. The mean age was 70.7 years (SD = 6.4) for men and 70.5 years (SD = 6.7) for women. Of the 2809 subjects, 2010 (71.5%) had no formal education, 607 (21.6%) completed 1-6 years of education, and 173 (6.2%) completed more than 6 years of school education. The prevalence of CI was 35.6% (95% CI: 33.8-37.4) for both genders when the cutoff point of 23/24 was used. However, when the cutoff point was altered with respect to different education levels, the prevalence of CI was 7.0%. For each item of the CMMSE, increased years of education correlated with a higher item score, with the exception of the 'Naming' item score. This study demonstrates that screening of CI using the AEL cutoff scores is feasible in a low-education population. Determining whether the 23/24 cutoff point is suitable for the Chinese people requires future prospective studies in a large Chinese population.

Gender-dependent associations between socioeconomic status and tooth loss in working age people in the Study of Health in Pomerania (SHIP), Germany

Individual impact and the effect magnitude of socioeconomic key indicators (income, education and occupation) and of gender on oral health are ambiguous. In primary analyses of cross-sectional data among participants of the Study of Health in Pomerania (north-east Germany), women with low school education and low income were at highest risk for missing teeth, whereas being single was a risk indicator for missing teeth in men. Using the 5-year follow-up of this study, we aimed at verifying these findings and at investigating the gender-dependent impact of key socioeconomic indicators on tooth loss. The longitudinal data originate from 1971 subjects (1062 women) aged 25-59 enrolled from 1997 to 2001 and again from 2002 to 2006. The effects of marital status, household income, school education and occupational prestige for tooth loss were examined by gender using negative binomial regression analyses. Low education and low income were moderately [relative risks (RR) between 1.6 and 2.0] associated with tooth loss among both women and men, whereas occupational prestige was not. After multiple imputations of missing data, less-educated women with lower income exhibited the highest risk of tooth loss [RR=3.1; 95% confidence interval (CI)=1.7-5.5 for <10 years of school education and the lowest income tertile] and tooth loss was more likely in single men (RR=1.5; 95% CI=1.0-2.2) than in single women (RR=0.9; 95% CI=0.6-1.3). The primary cross-sectional results were partly confirmed. Socioeconomic factors help to explain differences in tooth loss, although the causal pathways are speculative. To improve dental health, the policies should target not only the individual, e.g. oral health promotion, but also an entire population by better education and higher wage employment.

Gibt es soziale Ungleichheiten in der Inanspruchnahme der onkologischen Rehabilitation bei Mammakarzinompatientinnen?

Using data from a sample of breast cancer patients it was examined whether the utilisation of inpatient rehabilitation after breast cancer surgery within one year of primary therapy is unequally distributed. Furthermore, it was considered which reasons are associated with the omission of rehabilitation. Subjects were women after primary manifestation of breast cancer (stages: T(1)-T(3); N(0)-N(2); M(0)) aged 25-70 years. The data were collected as part of an ongoing prospective study on the role of social factors in the long-term course of breast cancer. Patients were interviewed immediately after primary surgery and a second time 1 year later. Interviews were performed by specially trained interviewers using semi-structured schedules. 3 gynaecological clinics in Hannover were involved. Logistic regression models were used for performing the main analyses. The data of 238 patients were used; 150 (63.3%) of them went to inpatient rehabilitation. Women with 12/13 years of school education were less likely to go to a rehabilitation clinic than women with lower qualifications; no social gradients in terms of occupational position emerged. A strong predictor for rehabilitation was chemotherapy, and in employed women radiotherapy was associated with lower utilisation. The reasons for not going to rehabilitation appear to be rather personal. They were motivated by patients' avoidance of being faced with cancer, and by the desire to take up the every day life that was interrupted by disease. These reasons are not socially patterned. We found no evidence for social barriers for utilising inpatient rehabilitation, but rather that medical and particularly individual reasons apply.

No-shows, drop-outs and completers in psychotherapeutic treatment: Demographic and clinical predictors in a large sample of non-psychotic patients

Background: A primary challenge in mental health services is a high rate of non-attendance (i.e. no-show and drop-out) for patients referred to treatment for psychiatric disorders. Aim: The aim of the present study was to assess the influence of demographic and clinical variables on mental health treatment attendance and to investigate differences in predictors for no-shows and drop-outs. Methods: A naturalistic study of 2473 non-psychotic consecutive patients offered psychotherapeutic treatment at a community mental health centre in Denmark. Fifteen demographic and clinical variables were recorded at assessment. Bivariate and multiple logistic regression analyses were conducted to investigate the associations between these variables and no-show and drop-out. Results: Of the 2473 participants, 668 (27.0%) did not show up for treatment, whereas 290 (11.7%) dropped out of treatment. Regression analysis showed that the significant predictors of treatment no-show were: age below 25, no more than the compulsory 9 years of school education, no sick leave, a diagnosis of personality disorder, a Global Assessment of Functioning score (GAF) below 40 or above 70, no previous psychiatric/psychological treatment, no use of antidepressants and substance abuse. The significant predictors of treatment drop-out were: age below 45, no more than the compulsory 9 years of school education or up to 11 years of school education, no vocational/university education, unemployment and substance abuse. Conclusion: No-show was predicted by both demographic and clinical factors, whereas drop-out was predicted by demographic factors and substance abuse as the only clinical factor. Results and strategies to reduce non-attendance are discussed.

Predictive modeling of health care costs: do cardiovascular risk markers improve prediction?

To investigate the ability of multiple cardiovascular disease (CVD) markers to predict future health care costs. CVD markers included traditional risk factors (smoking status, body mass index, waist circumference, alcohol intake, diabetes, total : high-density lipoprotein cholesterol ratio, actual hypertension, physical activity) and newer markers (carotid intima-media thickness, hemoglobin A1c, apolipoprotein B : apolipoprotein A-1 ratio, lipoprotein (a), leukocyte count, high-sensitive C-reactive protein, plasma fibrinogen, estimated glomerular filtration rate, urinary albumin : creatinine ratio). The study sample consisted of 2233 participants without history of myocardial infarction, stroke, heart failure, and angina pectoris at baseline (50.6% women; mean age 60.9 years; age range 45-81 years) from the cohort Study of Health in Pomerania, Germany (median follow-up 5 years). Predictive modeling revealed that a basic model with sex, age, years of school education, insurance status, and income explained 0.9% in baseline total cost variation and 1.5% in total cost variation at 5-year follow-up. The incorporation of a combination of significant CVD markers resulted in an increase in the R2 for total costs of 70% at baseline and 69% after 5 years, with a final R2 of 0.030 at baseline and an R2 of 0.048 at 5-year follow-up. Our data suggest that for individuals without history of CVD, the simultaneous addition of several CVD risk markers improves predictive modeling of future health care costs beyond that of a model that is based on established health care predictors.

Compliance with methotrexate treatment in patients with rheumatoid arthritis: influence of patients’ beliefs about the medicine. A prospective cohort study

Objective of the study is to investigate how compliance during the first year of methotrexate (MTX) treatment in rheumatoid arthritis (RA) is influenced by the patients' perception of the necessity for and concern about MTX, the patients' functional disability, and the dose of MTX. A total of 126 RA patients completed a questionnaire at start of MTX treatment and after 9 months. The MTX compliance was measured by using the Compliance Questionnaire Rheumatology (CQR). The prevalence of having a CQR score in the bottom quartile was stratified according to age, gender, the duration of RA, MTX dose, years of school education, functional disability, use of folic acid, and co-morbidity. Crude and adjusted prevalence ratios (PR) with 95% confidence intervals (CI) were calculated by using log-binomial regression. The necessity and concern scales of the Beliefs about Medication Questionnaire were dichotomised into high perception of MTX necessity and low concern about MTX treatment, and the crude and adjusted PR of having a CQR score in the bottom quartile were estimated. The prevalence of having a CQR in the bottom quartile was 23%, both at baseline and after 9 months, and this finding was not associated with the MTX dose level or the patients' functional disability. Among patients with a CQR in the bottom quartile, the prevalence of having low perceptions of MTX necessity was 37.1 versus 14.0% for patients with high perceptions of necessity [adjusted PR: 0.3 (95% CI 0.2-0.8)]. The same tendency was seen after 9 months. The prevalence of having a CQR in the bottom quartile or not was almost equally distributed among patients who had high or low concerns about treatment at baseline. After 9 months, however, the prevalence of having a CQR in the bottom quartile was 18.9% for patients who had low concerns about the MTX treatment, versus 37.7% for patients who had higher concerns about the treatment [adjusted PR: 0.5 (95% CI 0.2-1.3)]. During the first year of treatment, compliance with MTX treatment among RA patients could be explained by strong perceptions of a personal need for the treatment. Compliance did not seem to be influenced by the patients' functional impairment or the MTX dose level.

Effect of WHO Newborn Care Training on Neonatal Mortality by Education

Ninety-nine percent of the 4 million neonatal deaths per year occur in developing countries. The World Health Organization (WHO) Essential Newborn Care (ENC) course sets the minimum accepted standard for training midwives on aspects of infant care (neonatal resuscitation, breastfeeding, kangaroo care, small baby care, and thermoregulation), many of which are provided by the mother. The aim of this study was to determine the association of ENC with all-cause 7-day (early) neonatal mortality among infants of less educated mothers compared with those of mothers with more education. Protocol- and ENC-certified research nurses trained all 123 college-educated midwives from 18 low-risk, first-level urban community health centers (Zambia) in data collection (1 week) and ENC (1 week) as part of a controlled study to test the clinical impact of ENC implementation. The mothers were categorized into 2 groups, those who had completed 7 years of school education (primary education) and those with 8 or more years of education. ENC training is associated with decreases in early neonatal mortality; rates decreased from 11.2 per 1000 live births pre-ENC to 6.2 per 1000 following ENC implementation (P < .001). Prenatal care, birth weight, race, and gender did not differ between the groups. Mortality for infants of mothers with 7 years of education decreased from 12.4 to 6.0 per 1000 (P < .0001) but did not change significantly for those with 8 or more years of education (8.7 to 6.3 per 1000, P = .14). ENC training decreases early neonatal mortality, and the impact is larger in infants of mothers without secondary education. The impact of ENC may be optimized by training health care workers who treat women with less formal education.

Contribution of smoking and air pollution exposure in urban areas to social differences in respiratory health

BackgroundSocio-economic status, smoking, and exposure to increased levels of environmental air pollution are associated with adverse effects on respiratory health. We assessed the contribution of occupational exposures, smoking and outdoor air pollution as competing factors for the association between socio-economic status and respiratory health indicators in a cohort of women from the Ruhr area aged 55 at the time of investigation between 1985 and 1990.MethodsData of 1251 women with spirometry and complete questionnaire information about respiratory diseases, smoking and potential confounders were used in the analyses. Exposure to large-scale air pollution was assessed with data from monitoring stations. Exposure to small-scale air pollution was assessed as traffic-related exposure by distance to the nearest major road. Socio-economic status was defined by educational level. Multiple regression models were used to estimate the contribution of occupational exposures, smoking and outdoor air pollution to social differences in respiratory health.ResultsWomen with less than 10 years of school education in comparison to more than 10 years of school education were more often occupationally exposed (16.4% vs. 10.1%), smoked more often (20.3% vs. 13.9%), and lived more often close to major roads (26.0% vs. 22.9%). Long-term exposure to increased levels of PM10 was significantly associated with lower school education. Women with low school education were more likely to suffer from respiratory symptoms and had reduced lung function. In the multivariate analysis the associations between education and respiratory health attenuated after adjusting for occupational exposure, smoking and outdoor air pollution. The crude odds ratio for the association between the lung function indicator FEV1 less than 80% of predicted value and educational level (<10 years vs. >10 years of school education) was 1.83 (95% CI: 1.22–2.74). This changed to 1.56 (95% CI: 1.03–2.37) after adjusting for occupational exposure, smoking and outdoor air pollution.ConclusionWe found an association between socio-economic status and respiratory health. This can partly be explained by living conditions indicated by occupational exposure, smoking behaviour and ambient air pollution. A relevant part of the social differences in respiratory health, however, remained unexplained.

Newborn Aides: an innovative approach in sick newborn care at a district-level special care unit.

A Sick Newborn Care Unit (SNCU), established in a district hospital in India, substantially reduced the neonatal mortality rate in the district; it, however, suffered from a dearth of trained nurses. Local girls with 10-12 years of school education underwent structured and hands-on training for six months, followed by a six-month internship at the SNCU and were assigned to it as stipendiary 'Newborn Aides'. Based on the results of formal examinations, internal on-the-job assessment and interview of doctors, nurses, and parents and their technical skills and motivation were rated very high. Although the incremental cost of training is small, the cost of sustaining them, i.e. stipend and replacing attrition, needs to be addressed. Trained Newborn Aides may substantially alleviate human-resource constraint for SNCUs and Sick Newborn Stabilization units in smaller peripheral hospitals for care of sick newborns at an affordable cost.

Gender differences in brain reserve

Neuropathological studies suggest that the association between neurodegenerative brain damage and clinical symptoms may be stronger in women than in men. To test the hypothesis that cerebral metabolic deficits due to neurodegeneration are more pronounced in men than in women at the same level of clinical disease severity. 93 patients with mild Alzheimer's disease (AD; 50 men, 43 women) underwent an extensive clinical and neuropsychological examination and (18)F-FDG PET imaging at a university-based outpatient unit for cognitive disorders. An analysis of covariance (with age, total score of the CERAD neuropsychological battery, and years of school education as covariates) was conducted in each study group to identify gender differences in glucose metabolism. Controlling for age, education, and clinical severity, cortical regions were identified,where glucose metabolism was significantly reduced in men as compared with women. These regions were located in areas typically affected by AD pathology (right inferior frontal, superior temporal and insular cortex, and hippocampus). These data suggest that the same clinical severity of dementia is associated with greater reductions in cerebral metabolism in men than in women suggesting a greater degree of brain reserve in men.

Cerebral Metabolic Correlates of the Clinical Dementia Rating Scale in Mild Cognitive Impairment

Mild cognitive impairment (MCI) is often a prodromal state of Alzheimer's disease (AD). Imaging studies have shown that metabolic deficits in cerebral regions known to be affected early by AD pathology are predictive of progression to AD. In the present article, the authors examine associations between clinical impairment (Clinical Dementia Rating scale sum of boxes [CDR-SB]) and regional deficits in glucose utilization in a sample of 41 patients with MCI, who underwent cerebral 18F-FDG PET for the measurement of regional glucose metabolism. A linear regression analysis with CDR-SB score as the independent variable and glucose metabolism as the dependent variable, adjusted for age, gender, and years of school education, was conducted in voxel-by-voxel fashion in SPM2. The regression analysis revealed a significant negative association between CDR-SB score and glucose metabolism in the right posterior cingulate gyrus (P < .001, uncorrected for multiple comparisons), which was independent from demographical variables. The authors conclude that clinical severity of impairments is already correlated with deficits in glucose metabolism in the stage of MCI.

Male gender is associated with greater cerebral hypometabolism in frontotemporal dementia: evidence for sex‐related cognitive reserve

Neuropathological studies suggest that the association between neurodegenerative brain damage and clinical symptoms may be stronger in women than in men; therefore women are more likely to express neurodegeneration as clinical dementia. Furthermore, a recent 18F-FDG PET study explored gender differences in the regional cerebral metabolic rate of glucose (rCMRglc) in patients with Alzheimer's disease and found that, at the same level of severity of cognitive impairment, men showed a significantly greater hypometabolism than women. This suggests that men can compensate more pathology than women. To test the hypothesis that cerebral metabolic deficits due to neurodegeneration are more pronounced in men than in women with frontotemporal dementia (FTD), controlling for cognitive impairment. Twenty-nine patients with FTD (20 men, nine women) underwent an extensive clinical examination and 18F-FDG PET imaging at a university-based outpatient unit for cognitive disorders. An analysis of covariance (with age, total score of the CERAD neuropsychological battery, and years of school education as co-variates) was conducted to identify gender differences in glucose metabolism. Frontal cortical regions were identified where rCMRglc was significantly reduced in men as compared with women. These regions were located in the left middle, superior, and inferior frontal gyri and the right anterior cingulate, and superior frontal gyri (p < 0.001 uncorrected for multiple comparisons). The same level of severity of cognitive symptoms is associated with a more pronounced functional brain damage in male than in female patients with FTD, suggesting a greater degree of cognitive reserve in men.

Características relacionadas ao primeiro e último parto por cesárea

To study the association between first and last caesarian sections with tubal sterilization; to determine length of reproductive life after the first delivery. From February to October 2001 in a university hospital, interviews were carried out with 653 women having had at least two pregnancies. Of these women, 172 had a first caesarian section; 294 had a last caesarian section. Variables were social demographic characteristics, obstetric history and characteristics of the first and last deliveries and tubal sterilization. Bivariate analysis was performed, followed by multiple regression analysis calculating the adjusted odds ratio. Women who had undergone tubal sterilization were divided into age groups of 25 to 44 and >45 years in a percentile distribution. The Wilcoxon test was used to analyze age at tubal sterilization and length of reproductive life after the last delivery. The study was approved by the Ethics Committee. Of these women, 89% completed<8 years of school education and 78% were Caucasian. On multiple regression analysis, there was an association between the first and last caesarian section (OR=15.28, 95%CI 8.54 to 27.36), having a partner (OR=3.87, CI95% 1.63 to 9.17) and giving birth in the '70s, '80s or '90s (OR=4.43, 95%CI 1.37 to 14.27), (OR=6.11, 95%CI 1.47 to 25.47) and (OR=6.67, 95%CI 1.21 to 40.26), respectively. The last caesarian section was associated with intrapartum tubal sterilization (OR=14.09, 95%CI 7.37 to 26.97), giving birth in the '70s, '80s or '90s (OR=1.81, 95%CI 1.06 to 3.09), (OR=5.53, 95%CI 3.18 to 9.61) and (OR=5.90, 95%CI 3.03 to 11.48), respectively, family income of >5 minimum wages (OR=2.41, 95%CI 1.42 to 4.08) and age at first delivery>25 years (OR=1.80, 95%CI 1.01 to 3.22). Mean age at sterilization was 29.0 and 33.2 years in women aged 25 to 44 years and >45 years, respectively (p<0.001). The duration of the reproductive period after the first delivery was 9.0 and 11.4 years for the same groups (p<0.001). The first caesarian section was associated with the last caesarian section. The last caesarian section was associated with intrapartum tubal sterilization. Age at sterilization was lower and the reproductive period was shorter among younger women.

HIV-1 Infection as a Risk Factor for Incomplete Childhood Immunization in Zambia

Immunizations are of particular importance for human immunodeficiency virus type 1(HIV-1)-infected children as they are at increased risk of severe disease and death from several vaccine-preventable diseases. Outside the United States, however, research on the impact of the HIV-1 epidemic on childhood immunization coverage is sparse. We conducted a nested case-control study in hospitalized children with measles to assess whether HIV-1 infection was a risk factor for incomplete immunization with diphtheria-tetanus-pertussis vaccine (DTP) and oral polio vaccine (OPV). Of 473 children, whose immunization status was determined from the immunization record or maternal recall, 23% were incompletely immunized and 19% were HIV-1 infected. After adjusting for age, sex, and measles vaccination status, HIV-1 infection was significantly associated with incomplete immunization with DTP and OPV (adjusted OR 1.9; 95% CI 1.1, 3.3). In a subset of children for whom information on maternal education was available, less than 7 years of school education was a risk factor for incomplete immunization (adjusted OR 3.7; 95% CI 1.8. 7.5). Children from homes with more than three children were twice as likely to be incompletely immunized as those from homes with one to three children. Our findings suggest that HIV-1-infected children are at increased risk of vaccine-preventable diseases not only because of impaired immune responses but because of lower rates of vaccine coverage.
