The relationship between learning, health beliefs, weight gain, alcohol consumption, and tobacco use of pregnant women

Strychar, Irene January 1988 (has links)
Understanding how women learn during pregnancy is the foundation for planning prenatal education programs. To date, adult educators have not investigated, in any depth, the learning process during pregnancy. The purpose of this study was to examine learning during pregnancy and relate this learning to learning outcomes. The principal research questions were: "What are the learning patterns of pregnant women?" and "What is the relationship between learning and health behavior of pregnant women?" It is unknown whether learning during pregnancy is directly associated with behavior or mediated through health beliefs. The objectives of this research were to identify pregnant women's health behaviors, learning patterns, and health beliefs. The three health behaviors examined in this study were eating, drinking, and smoking. These behaviors were operationalized in terms of their outcomes: weight gain, alcohol consumption, and tobacco use. These factors are amenable to an education intervention and are behavioral risk factors associated with low birth weight. The process of investigating learning patterns consisted of identifying: what was learned during the pregnancy, which resources were utilized, what advice was given, what amount of time was spent in learning, who initiated the learning episodes, and what learning transaction types emerged. Determining learning transaction types was based upon an adaptation of Tough's (1979) concept of planners and Knowles's concept of self-directed learners. The process of investigating health beliefs consisted of identifying pregnant women's concerns, perceived risk, perceived use of the information, and perceived barriers, defined according to an adaptation of the Health Belief Model. The principal hypotheses of the study were: (1) self-initiated learning will be positively correlated with knowledge scores, (2) self-initiated learning will be positively correlated with ideal health behaviors, and (3) health beliefs will be positively correlated with ideal health behaviors: ideal weight gain during pregnancy, reduced alcohol consumption, and reduced cigarette smoking. The research, an ex post facto design, involved a one hour structured interview with women within the week following delivery of their infants in hospital. A proportional sample of 120 primigravidas was selected from seven hospitals with average number of monthly births greater than 100. Reporting of results was based upon 120 interviews conducted as part of the main sample and eight interviews conducted during the pilot study. Pilot responses were included because these responses were similar to responses provided by the main sample, with the exception of health belief data. One case was excluded from the sample, making for N = 127. Data analyses were based upon the entire sample N = 127, with the exception of health belief measures. Since alcohol and smoking health belief questions were administered to drinkers and smokers and since health belief measures related to weight gain, alcohol, and smoking were missing data, health belief analyses were based upon N=123 for weight gain, N = 88 for alcohol, and N = 43 for smoking. Women had spent an average of forty-one hours learning about weight gain, alcohol consumption, and tobacco use during pregnancy. The principal resources used were: reading materials, physicians, family members, and prenatal classes. The majority of pregnant women had engaged in other-initiated learning episodes in the one to one setting, that is with a health professional, family member, or friend. Self-initiated learning about weight gain was associated with higher knowledge scores and ideal prenatal weight gain (p≤0.05); and, weight gain health beliefs were negatively correlated with ideal prenatal weight gain (p≤0.05). Finding a negative correlation, in contrast to the predicted positive correlation, may have been due to the fact that in a retrospective study the behavior precipitated reporting of health beliefs. Other-initiated learning about alcohol was associated with higher knowledge scores and reduced alcohol intake (p≤0.05); however, alcohol health beliefs were not associated with reduced alcohol intake. For smoking, neither self-initiated nor other-initiated learning was associated with knowledge scores or reduced cigarette smoking; however, a low degree of perceived risk was predictive of reduced cigarette smoking (p≤0.05). Knowledge about tobacco use was positively correlated with health beliefs, suggesting that learning may be indirectly related to smoking behaviors. This study contributes to the knowledge about learning during pregnancy by providing a descriptive profile of learning patterns during pregnancy, and by examining the relationship between learning, health beliefs, and behavior. Fostering a learning environment which stimulates self-initiated learning may assist women reach ideal weight gain during pregnancy. For alcohol, encouraging health professionals, family members, and friends to initiate learning about the hazards of consuming alcohol during pregnancy seems warranted. Self-initiated learning may not be superior to other-initiated learning but may be topic specific, due to the nature of the health behaviors examined. Identification of women's smoking health beliefs seems warranted during prenatal education. Further research is required to better understand the role of learning with respect to changing smoking behaviors during pregnancy. / Education, Faculty of / Educational Studies (EDST), Department of / Graduate

Exploring cultural beliefs and practices for the use of herbal medicine and remedies during pregnancy in Lesotho

Lekhotsa, Thakanyane Juliah 01 1900 (has links)
Summaries in English and Sesotho / This qualitative, exploratory, descriptive study explored culturally sensitive health information about the use of herbal medicine by pregnant women in Lesotho, in order to provide culturally sensitive health advice to pregnant women. Pregnant women used herbal medicine and remedies during pregnancy resulted in still births and complications during labour. Data on the beliefs and practices of fifteen purposively and conveniently sampled pregnant women attending a rural antenatal clinic was collected through semistructured interviews and analysed using Colaizzi’s seven-step method. Ethical principles and strategies to ensure trustworthiness were applied. One central theme emerged: ‘Women believe that the use of herbal medicine and remedies is a traditional practice that pregnant women need to follow due to culture’. The cultural beliefs and practices of the women were deeply rooted in Basotho culture, which guided the use of herbal medicine. However, some considered herbal medicines to be harmful, as the dosage and content of these medicines vary. Nurses are therefore key to providing culturally sensitive health care advise on using herbal medicine during pregnancy. / Boithuto bona ba boleng bo botle, bo hlalosang le ho fumaneng tlhaiso-leseling e mabapi le bophelo bo botle mabapi le ts’ebeliso ea meriana ea litlama ke basali ba baimana Lesotho, ele ho fana ka likeletso tsa bophelo bo botle ba setso.

Vythilingum, B. et.al. 2012. Risk factors for substance use in pregnant women in South Africa. South African medical journal, 102(11):851-854 / ENGLISH ABSTRACT: Objectives. To study the prevalence of alcohol and substance use in a South African antenatal population and its correlates with sociodemographic factors, depression and perceived stress. Methods. A prospective self-report study on all women presenting for their first antenatal visit who consented to the study at a midwife obstetric unit (MOU) in the East Metropole district, Cape Town, using the Alcohol Use Disorders Identification Test (AUDIT), Drug Use Disorders Identification Test (DUDIT), Edinburgh Depression Scale (EDS) and Perceived Stress Scale (PSS). Statistical analyses using the chi-square test, separate one-way analyses of variance (ANOVA) and logistic regression analyses were performed as appropriate. Outcome measures were depression, alcohol use and substance use. Results. The questionnaire was completed by 323 women. During pregnancy 36.8% of women smoked, 20.2% used alcohol and 4% used substances. Using EDS cut-off scores of 12 and 15, respectively, 48.9% and 33.6% of the sample had scores consistent with major depression. An EDS cut-off score of 12 was significantly associated with both alcohol use (25.9% v. 15.2%, p=0.019) and risky drinking (76.9% v. 36.8%, p=0.04), while an EDS cut-off score of 15 was significantly associated with substance use (8.2% v. 1.4%, p=0.004) as well as alcohol dependence (23.1% v. 3.1%). Conclusions. We found high rates of both alcohol abuse and antenatal depression, and a significant association between depression, substance use and alcohol abuse; EDS scores greater than 12 could be used to identify women at risk of alcohol dependence and/or substance abuse. / Publishers' version

The prevalence of members of the "red complex" in pregnant women as revealed by PCR and BANA hydrolysis.

Bayingana, Claude January 2005 (has links)
Increased levels of oestrogen and progesterone during pregnancy may lead to periodontal disease. The anaerobic Gram-negative bacteria called red complex (Porphyromonas gingivalis, Tannerella forsythensis and Treponema denticola) are frequently associated with periodontal disease. Periodontopathogens produce toxins and enzymes which can enter the bloodstream and cross the placenta to harm the foetus. The response of the mother&rsquo / s immune system to infection by these periodontopathogens, brings about the release of inflammatory mediators which may trigger preterm labour or result in low birth-weight infants. The purpose of this study was to examine the prevalence of red complex, using BANA and PCR in subginginval plaque samples from pregnant women. Subgingival plaque samples were obtained from pregnant women between the ages of 17 to 45 years attending a Mitchells Plain ante-natal clinic. Plaque samples were analyzed by the enzymatic BANA-test for detection of the presence of red complex and DNA was extracted and analyzed using 16 rDNA-Polymerase Chain Reaction (PCR).<br /> <br /> Seventy-nine percent of pregnant women showed gingival index scores of &ge / 1 of which 74.24% harboured by at least one of the members of the red complex. P.gingivalis was the most prevalent of the three members of the red complex. Findings of this study confirmed a need for dental preventive measures in pregnant women and microbial monitoring of suspected periodontopathogenes. This could be achieved by joint cooperation between Maternity Obstetric Units (MOU), Dentistry and oral microbiology departments. The results of this study revealed that although PCR is more sensitive than BANA in detecting members of the red complex, BANA showed a better association with the indices used to diagnose periodontal disease.

Association between betel nut consumption and folate deficiency among pregnant women in Matlab, Bangladesh

Kader, Manzur January 2011 (has links)
Background:  Betel nut (BN) or Areca nut (AN) chewing habits on its own or with other ingredients including chewing tobacco are highly prevalent in many South East Asian countries as well as among the migrants from these countries residing around the world. The major alcaloid arecoline in betel nut has been found to carcinogenic and to be associated with a range of health risks, including negative effects on pregnancy outcomes.  It is also reportedly associated with nutritional deficiencies including lower folate status among men and women. Pregnancy imposes stress on folate stores because of increased requirements for growth of maternal tissues, the fetus and the placenta.  Folate deficiency during pregnancy is a major public health concern as it is associated with many adverse health outcomes including neural tube defects, low birth weight, preterm birth, delayed maturation of the nervous system, growth retardation and megaloblastic anemia. Aim: To evaluate the association between betel nut use and folate status among pregnant women in Matlab, Bangladesh. Design: A secondary analysis of data from the Maternal and Infant Nutrition Intervention in Matlab (MINIMat) trial.  A sub sample of pregnant women aged 14-50 years and living in the study area Matlab with available serum folate measurements (N= 730) was included in this study. Outcome variable was folate level and folate deficiency and the independent variable was betel nut consumption.  Logistic regression analysis and analyses of covariance (ANCOVA) were done. Results were adjusted for potential confounders. Results: Two-thirds (63%) of the women consumed betel nut and 17% had folate deficiency. Women who consumed betel nut combined with  chewing  tobacco were 2.57 times more likely to have folate deficiency (OR = 2.57; 95% CI = 1.23-5.36; p =0.012;) and  betel nut consumption 2-3 times/day was significantly associated with folate deficiency among users (OR = 2.51; 95% CI = 1.07–5.92; p =0.035). Mean serum folate levels were significantly lower among betel nut users as compared to non-users. Conclusion: Betel nut consumption combined with chewing tobacco is associated with lower serum folate level or folate deficiency among pregnant women in Matlab in Bangladesh. Strategies are needed for prevention and control of betel nut consumption in order to prevent adverse health outcomes. There is a need of more knowledge regarding betel nut use and other combined substances to distinguish their individual effects on folate deficiency.

Exploring patient and health professional use, views and attitudes towards complementary and alternative medicines during pregnancy

Abdul Rouf, P. V. January 2015 (has links)
The aim of this doctoral research was to explore CAM use in pregnancy from the perspectives of pregnant women and health professionals. The research was conducted in four phases: a systematic review of the published literature from 2008-2012; cross sectional surveys of two cohorts of women during the first and last trimester; and a cross sectional survey of health professionals (midwives, obstetricians, anaesthetists) at Aberdeen Maternity Hospital. The systematic review reported a significant proportion of women used CAM during pregnancy with prevalence rates ranging from 5.8% to 74.2%. The study of health professionals identified that more than 30% of respondents have prescribed, referred or advised the use of CAM to pregnant women. The main associated factor for CAM use was, 'personal use of CAM', with an odds ratio of 8.26 (95% CI 3.09–22.05; P < 0.001). Two thirds of women (63%) reported using CAM, excluding vitamins and minerals, during early pregnancy. The independent predictors of CAM use identified were: use by family and friends (OR 4.1, 95% CI 2.3–7.3, p < 0.001); ethnicity (non-white British) (OR 3.4, 95% CI 1.8–6.8, p < 0.001); and use prior to pregnancy (OR 2.4, 95% CI 1.2–4.8, p = 0.014). Two thirds of women (61.4%) reported using CAM, excluding vitamins and minerals, during the third trimester. The independent associated factors for CAM medicine use identified were: CAM use before pregnancy (odds ratio [OR] 4.36, 95% confidence interval [CI] 2.39–7.95, P<0.001); a university education (OR 2.41, 95% CI 1.46–4.0, P<0.001), and CAM use by family or friends (OR 2.36, 95% CI 1.61–3.47,P<0.001). The lack of an evidence based approach together with the reliance on the advice of family and friends is of concern given the lack of robust data of efficacy and safety. To date, four peer reviewed papers from this doctoral research have been published.

Prevalence of positive rapid plasma reagent tests (RPR) in pregnent women: a real or assumed decrease?

Moodley, Serasheni 29 September 2008 (has links)
ABSTRACT Introduction The aim of this study was to determine the current RPR positive prevalence rate at the Johannesburg Hospital and to determine whether there has been a significant decrease in the prevalence rate of RPR positive tests. Patients and Methods A retrospective analysis of all RPR results within labour ward registers was performed. A sample from 01/08/02 to 31/01/03 was used to determine the current RPR positive prevalence rate. The results from the current period were then compared to the results from a similar study in 1996. Results of two months, six months apart, of each year between these periods were also analyzed in order to determine the trend of RPR positive prevalence rates. Results The RPR prevalence rate was 4.4% compared to 19.5% in 1995/96 (p < 0.0001). Results obtained from the intervening years showed a statistically significant decrease. Conclusion RPR positive prevalence rates at Johannesburg Hospital have decreased significantly in recent years.

Can a routine peri-partum HIV counselling and testing service for women improve access to HIV prevention, early testing and treatment of children?

Technau, Karl-Gunter 19 April 2010 (has links)
MSc (Med), Paediatrics and Child Health, Faculty of Health Sciences, University of the Witwatersrand, 2009 / Context Prevention of mother to child transmission (PMTCT) of HIV relies on identification of HIV-positive pregnant women at the first antenatal visit and at time points thereafter. As not all women who attend antenatal care initially agree to test or maintain an HIV-negative status the lack of re-establishing HIV prevalence at delivery may result in missed prevention opportunities and a false impression of PMTCT coverage. Objectives To assess whether a routine peri-partum HIV counseling and testing service improves access to HIV prevention, testing and care of infants by identifying additional HIV-positive women at the time of delivery. To assess the effect on the PMTCT coverage indicator when HIV prevalence is reestablished in the delivery population. Design and Patients All women 18 years or older with live births in the labour and postnatal wards of the Rahima Moosa Mother and Child Hospital (RMMCH) were interviewed and invited to enrol irrespective of their need to retest/test for HIV or their potential refusal of an HIV test. Rapid HIV antibody tests were offered to women who had no HIV result, reported an HIV-negative result performed more than six weeks prior to delivery or reported an HIV result discrepant with her documented result. vi Test acceptance and HIV prevalence were calculated for the enrolled population. The rate of return and results for early infant diagnosis in HIV-exposed infants and the follow-up of infected infants were documented. HIV polymerase chain reaction (PCR) results for infants not returning to the facility were retrieved from the National Health Laboratory Services database. Results Between 9th April 2008 and the 23rd of September 2008 there were 5169 women with live births. A total of 3684 (71.3%) of the 5169 women delivering were interviewed and 2419 (46.8%) were enrolled. Of the women enrolled, 2140 (88.5%) reported a known HIV status and 490 (22.9%) of these were HIV-positive. After counseling and testing, an additional 101 HIV-positive women were identified increasing the number of HIV-positive women by 20.6%. An additional 177 women were identified as being HIV-negative. The true infant PMTCT coverage increased by 17% as a result of newly identified HIV-positive women. Of 591 HIV-exposed infants identified, 284 (48.0%) underwent PCR testing at RMMCH or surrounding facilities and 16 (5.6%) tested PCR-positive. Of the infants expected to return to RMMCH for PCR testing 155/203 (76.4%) antenataly diagnosed versus 12/83 (14.5%) newly diagnosed women returned with their infants (p<0.001). Ten HIVinfected infants were diagnosed at RMMCH of which nine were in care with six initiated on antiretrovirals.
