The effects of an aerobic walking program, from 22 to 30 wk gestation, on aerobic fitness, vitamin B-6 status, and birth outcome was studied in 28 healthy, pregnant women aged 21-36 yr receiving vitamin-mineral supplements. Aerobic fitness was assessed by heart rate (HR) and relative oxygen consumption (VO₂, ml/kg/min) during 2 submaximal treadmill walking tests (22 and 30 wk). HR responses were significantly lower for walking subjects (W; n=18) compared to nonwalking (NW; n=10) at 2 and 4 min and near significance at 6 min of the 30 wk treadmill test. HR increased significantly at 2 min for NW from 22 to 30 wk. Oxygen consumption significantly decreased for W from 22 to 30 wk at 2, 4, and 6 min of exercise but remained unchanged for NW. Mean vitamin B-6 intake, minus the 10 mg supplement, was at least two-thirds the 1980 Recommended Dietary Allowance. Values for plasma total vitamin B-6 assessed microbiologically were in the low-normal range for only 3 subjects (1 W at 22 wk and 2 W at 30 wk). Values for plasma pyridoxal phosphate levels assessed radioenzymatically were in the low-normal range for only 2 subjects (1 W at 22 wk and 1 W at 30 wk). Birth weight, Apgar scores, and labor duration were similar for both groups. Participation in a walking program by pregnant women taking vitamin-mineral supplements slightly improved aerobic fitness without affecting vitamin B-6 status (probably due to the supplement usage) or birth outcome. / M.S.

This study evaluated the effects of participation in aerobic exercise on pregnancy outcomes. Pregnancy outcomes included type of delivery, length of labor, gestational age, neonatal birth weight, and maternal weight gain. The 137 nulliparas were categorized as active (N=44) or sedentary (N=93) based on self-reported aerobic exercise. Findings from this study suggest that pregnant women who were active during pregnancy were more likely to have vaginal deliveries than sedentary women. No significant differences between active and sedentary women were found in neonatal birth weight, maternal weight gain, length of labor, or gestational age.

Thesis (M.CUR.) --University of Limpopo, 2014 / Indigenous practices (IPs) are experiences generated by people who are living in a specific region context and a specific cultured group. IPs are shaped by cultural traits that are passed from one generation to the next. The practices are rooted and embedded in such a society and, therefore, the practices become part of the people’s lifestyle. It is difficult to try and change these practices, since people have adhered to them throughout their entire lives. The believe system plays a major role in health care seeking behaviour of individuals because they are informed by the IPs that are observed in their environment (Shaik & Hatcher, 2005). IPs are stored in people’s memories and are expressed in songs, dances, beliefs, rituals, cultural values, myths, and healing of diseases by using herbs. During pregnancy, IPs are still applied worldwide. Ayaz and Efe (2008) indicate that it occurs mostly in Turkey and Africa where women’s reassurance is depending on the local context and meaning of pregnancy. THE PURPOSE OF THE STUDY To determine indigenous practices of pregnant women at the Dilokong Hospital in the Greater Tubatse Municipality of the Limpopo Province.This was achieved by the exploring and describing the indigenous practices of pregnant women in the antenatal (ANC) clinic of the maternity ward at the Dilokong Hospital.. DESIGN AND METHOD A qualitative, descriptive, explorative and contextual research design was used for the participants to describe the indigenous practices by pregnant women. Data was collected by means of unstructured one-on-one interviews in maternity unit of the ANC clinic at the Dilokong Hospital of the Greater Tubatse Municipality. Ethical considerations as described by Denosa (2000) were adhered to in order to ensure the v quality of the study. The criteria for trustworthiness were observed as stipulated in Babbie and Mouton (2009).Fifteen pregnant women were interviewed. FINDINGS AND RECOMMENDATIONS Four themes with sub-themes emerged from the data analysis by using Tech’ṡ open coding approach (Creswell 2006, Botma, Greef, Mulaudzi & Wright, 2010). Four themes were emerged namely; indigenous practices based on ancestral knowledge; indigenous practices based on spiritual diviners versus church principles; restricted practices versus instructions followed during pregnancy and labour and indigenous practices during labour and delivery. It is recommended that a national IP strategy needs to be developed to provide a framework and platform to support and promote grass roots IPs into mainstream development in the health care system in relation to midwifery practice. CONCLUSION The study findings indicated that IPs were regarded as an honourable health intervention by THPs, families, and pregnant women. They showed trust in methods used to preserve pregnancy, labour, and delivery, although, the indigenous practices by pregnant women still continue. Indigenous practices such as cords around their waists, are still observed during physical examinations. However, there is a reduction of prescribed potions mixed with cool drinks for use to accelerate labour and to prevent negative consequences because the potential toxicity has been explained during the provision of health education. These findings call for health care professionals to emphasise training and workshops for the THPs church diviners that are the fundamental principle of effective implementation of IPs to enhance improvement in the prevention of complications during pregnancy, labour and delivery.

Background Excessive gestational weight gain (GWG) poses significant risk for maternal and neonatal health. Various guidelines have recommended healthy diets and enhancing physical activity during pregnancy to prevent excessive GWG. However, results of intervention studies are inconsistent in the developed countries, and there are no official guidelines and few interventions for GWG in China. This paper aims to review and synthesize relevant studies on diet and physical activity interventions to prevent excessive GWG so that practical suggestions can be provided to public health authorities in China. Methods This systematic review was performed using PubMed, Google and Google Scholar to search all relevant studies in English and randomised controlled trials (RCTs) that investigated diet and physical activity interventions to limit excessive GWG up to May 2014. The quality of included studies was assessed using CONSORT statement and JADAD scale. Results Nine studies describing diet and physical activity interventions to prevent excessive GWG were incorporated in the systematic review. Overall, the contents of interventions were diverse, which consisted of one-to-one counselling, and community-based physical activity interventions. Weekly mailed newsletters and supportive telephone calls were used as assistive tools to remind pregnant women of limiting excessive GWG. Seven studies showed less weight gain in pregnant women receiving the intervention, of which four studies demonstrated a reduction in excessive GWG in women with varying body mass index (BMI) spanning the normal, overweight and obese categories, while three studies reported a reduction of excessive GWG only in normal weight women and obese women need to be paid attention in the future. Conclusions The effectiveness of diet and physical interventions to limit excessive GWG may not be confirmed because of limited quality or sample size of intervention studies. However, studies have demonstrated reduction of excessive GWG during pregnancy, in addition to persistent healthy behaviours following such interventions during pregnancy. Further meta-analyses of RCTs studies should be done to confirm the effectiveness of such interventions among Chinese women. / published_or_final_version / Public Health / Master / Master of Public Health

The interrelation among maternal dietary intake, pregravid weight, amount and pattern of gestational weight gain and cigarette smoking in influencing the balance between fetal growth and maternal postpartum weight retention was in investigated in 1,330 healthy participants in the PEI Nutritional Counselling Program. Among nonsmokers, gestational weight gain was the main predictor of postpartum weight retention and explained 65.3% of its variability, while explaining only 4.7% of infant birth weight variability. Women with higher postpartum weight retention gained more weight during pregnancy and most of the difference between higher and lower weight retention groups occurred in the first 20 weeks. When comparing infant size between smoking and nonsmoking mothers, birth weight increased linearly with maternal weight gain in all weight status groups except in overweight nonsmokers where birth weight reached a plateau at weight gains $>$17 kg. Among smokers, infant length increased at a higher rate with weight gain than nonsmokers. Although higher weight gains seemed to partially mitigate the effect of smoking on the risk of small-for-gestational-age (SGA) infants, such risk remained $>$10% at elevated weight gains among underweight smokers. The effects of smoking in reducing maternal and infant weights were not mediated by lower energy intake, as smokers consumed more energy than nonsmokers after controlling for physical activity and pregravid weight. The independent relative risks of SGA infants due to maternal smoking, pregravid underweight and low weight gain, were 3.23, 1.80 and 1.72 respectively, implying that smoking has the greatest effect on SGA. Based on current smoking prevalence in Canada, the population etiologic fraction of SGA due to the direct effect of smoking is 30.8%; approximately twice that for maternal underweight or low weight gain. Efforts to increase infant birth weight through higher maternal weight gain would require impractically high ene

The purpose of this study was to determine the relationship- between prenatal weight gain relative to initial weight and change in smoking habits relative to prepregnancy smoking habits on infant birth weight. The convenience sample was 100 women who had been prenatal clients at a clinic for low income women and who delivered term infants during a one year period. Women were selected who had term deliveries and were without medical problems during the pregnancy.Prepregnancy weight-for-height was determined using the 1959 Metropolitan Life Insurance Table. Weight gain throughout the pregnancy was charted on the appropriate graph. Changes in smoking habits during the pregnancy were evaluated verbally. Roy's Adaptation Model was the conceptual framework for this study. The physiological mode of this model depicts people as individuals who are constantly adapting to a changing environment. Procedures for the protection of human subjects were followed.The first research question illustrated that women who gained adequate weight and reduced or quit smoking had infants with higher birth weights. The second research question showed that, overall, women who quit or reduced the amount smoked early in pregnancy had infants with higher birth weights than women who quit or reduced later in pregnancy or-who did not change smoking habits. The third research question determined that nonsmokers had infants with higher birth weights than smokers.Women who smoke will have infants with lower birth weights than those that do not smoke. Women with inadequate weight gains during pregnancy are more likely to have infants: with lower birth weights than women with adequate weight gains. Health care providers must be able to relay, the risks of inadequate weight gain and smoking to pregnant women. / School of Nursing
