Influence of antenatal physical exercise on haemodynamics in pregnant women: a flexible randomisation approach.

ABSTRACT: Normal pregnancy is associated with marked changes in haemodynamic function, however the influence and potential benefits of antenatal physical exercise at different stages of pregnancy and postpartum remain unclear. The aim of this study was therefore to characterise the influence of regular physical exercise on haemodynamic variables at different stages of pregnancy and also in the postpartum period.Fifty healthy pregnant women were recruited and randomly assigned (2 × 2 × 2 design) to a land or water-based exercise group or a control group. Exercising groups attended weekly classes from the 20th week of pregnancy onwards. Haemodynamic assessments (heart rate, cardiac output, stroke volume, total peripheral resistance, systolic and diastolic blood pressure and end diastolic index) were performed using the Task Force haemodynamic monitor at 12-16, 26-28, 34-36 and 12 weeks following birth, during a protocol including postural manoeurvres (supine and standing) and light exercise.In response to an acute bout of exercise in the postpartum period, stroke volume and end diastolic index were greater in the exercise group than the non-exercising control group (p = 0.041 and p = 0.028 respectively). Total peripheral resistance and diastolic blood pressure were also lower (p = 0.015 and p = 0.007, respectively) in the exercise group. Diastolic blood pressure was lower in the exercise group during the second trimester (p = 0.030).Antenatal exercise does not appear to substantially alter maternal physiology with advancing gestation, speculating that the already vast changes in maternal physiology mask the influences of antenatal exercise, however it does appear to result in an improvement in a woman's haemodynamic function (enhanced ventricular ejection performance and reduced blood pressure) following the end of pregnancy.ClinicalTrials.gov NCT02503995.

Project description:BackgroundAntenatal physical exercise has roles in health maintenance, prevention, and treatment of disease for pregnant women and fetuses. Different organizations and medical institutions prescribe regular physical exercise during the antenatal period. Despite this, the pregnant populations are less active and decrease their exercise levels during pregnancy than in their non-pregnant state. Therefore, this study aimed to assess antenatal physical exercise level and its associated factors among pregnant women in Hawassa city, Sidama regional state, Ethiopia.MethodsInstitutional based cross-sectional study design was employed, and 600 study participants were interviewed using a systematic sampling technique from 25th September/2021 to 25th November/2021. Data entry was made using Epi-Data software version 3.1 and exported to SPSS version 25 for analysis. A bivariate logistic regression assessed the association between each independent variable and the outcome variable. Explanatory variables with a p-value of less than 0.25 were a candidate for the multivariable logistic regression. Finally, variables with a p-value of less than 0.05 were declared as statistically significant and reported with their AOR and 95% CI.ResultIn this study, 25.5% of pregnant women had an adequate practice of antenatal physical exercise while 43.7% of pregnant women had an adequate level of knowledge on antenatal physical exercise An adequate practice of women's antenatal exercise is more likely to occur in women who are exposed to mass media (AOR: 2.43, 95% CI: 1.57, 3.78), Husband college and above educational level (AOR 1.57, 95% CI: 1.05, 6.12), having an adequate level of knowledge (AOR 2.12, 95% CI: 1.13, 3.37), and have of supporting facility (AOR: 2.29, 95% CI: 1.49, 3.51).ConclusionIn this study, three fourth of the study participants had an inadequate level of practice in antenatal physical exercise than the global standard. It shall be beneficial if the city health administration works towards improving pregnant women's knowledge and practice level on physical exercise by providing information using different media outlets. Healthcare providers should broadcast antenatal physical exercise prescriptions in integration with health-related programs.

Project description:Background The timing of initiation of first antenatal care visit is paramount for ensuring optimal care and health outcomes for women and children. However, the existing evidence from developing countries, including Ethiopia, indicates that most pregnant women are attending antenatal care in late pregnancy. Thus, this study was aimed to assess timely initiation of antenatal care and associated factors among pregnant women attending antenatal care services in Southwest Ethiopia. Methods Institutional based cross-sectional study was conducted among 375 pregnant women from April 15 to June 15, 2019 in Southwest Ethiopia. A structured and pre-tested face-to-face interviewer-administered questionnaire technique was used to collect data. Systematic random sampling technique was employed to recruit pregnant women. The data were entered into Epi data version 4.4.2 and analyzed using SPSS version 25. Frequency tables, charts and measures of central tendency were used to describe the data. The effect of each variable on timely initiation of antenatal care was assessed using bi-variable logistic regression. A multivariable logistic regression model was used to identify factors associated with timely initiation of antenatal care. The adjusted odds ratio with 95% confidence interval and p<0.05 was used to identify factors associated with timely initiation of antenatal care. Results The study revealed that 41.9% of pregnant women started antenatal care timely. Pregnant women who had good knowledge of timely initiation of antenatal care (AOR = 3.8, 95% CI: 2.2–6.5), planned to be pregnant (AOR = 5.1, 95% CI: 2.9–8.9), being primigravida (AOR = 2.6, 95% CI: 1.4–4.7) and confirmed their pregnancy by urine test (AOR = 4.1, 95% CI: 2.4–6.9) were found to be significant predictors for timely initiation of antenatal care. Conclusions Despite the efforts made to make ANC visit services freely available, timely initiation of antenatal care among pregnant women in the study area was low. Pregnant women who had good knowledge of timely initiation of antenatal care, planned to be pregnant, being primigravida and confirmed pregnancy by urine test were found to be significant predictors for timely initiation of antenatal care. Therefore, efforts that strengthen awareness on antenatal care and its right time of commencement, increase pregnant women’s knowledge of timing of antenatal care services and reducing unplanned pregnancies should be organized.

Project description:BackgroundExercise during pregnancy is among the cost-effective options that can significantly reduce the burden of chronic metabolic diseases leading to an adverse birth outcome. Despite the negative consequences of sedentary life among pregnant women, little is known about the pregnant mothers' knowledge, attitude, and associated factors toward exercise during pregnancy in Ethiopia, particularly in the study area.ObjectiveTo assess knowledge, attitude, and associated factors toward exercise during pregnancy among women attending antenatal care at Bahir Dar city, Northwest Ethiopia, 2020.MethodologyA health facility-based cross-sectional study design was employed among 475 pregnant women from March 12 to May 12, 2020. A systematic random sampling technique was used to select the study participants. Interviewer-administered questionnaire was used to collect the data from pregnant women attending the antenatal care unit. Data were coded and entered using Epidata version 3.1 and analyzed by Statistical Package for Social Science (SPSS) version 25. Binary and multivariable logistic regressions were used to identify possible determinants and an odds ratio was used to measure the strength of associations at a p-value of <0.05.ResultThe study showed that 55.8% (95% CI: 48.45-59.12) of pregnant women were knowledgeable about benefits and contraindication of exercise during pregnancy; 53.3% (95% CI: 49.05-57.62) of them had positive attitudes toward exercise during pregnancy. Educational status adjusted odd ratio (AOR) = 3.95 (95% CI: 1.712-9.108), practicing physical exercise before becoming pregnant AOR = 3.64 (95% CI: 1.091-12.118), and women who heard about exercise during pregnancy AOR = 4.74 (95% CI: 2.563-8.756) were found to have statistically significant association with knowledge of women about exercise during pregnancy. Women who were knowledgeable about exercise during pregnancy AOR = 4.45 (95% CI: 2.39-8.29) and women who heard about exercise during pregnancy AOR = 4.2 (95% CI: 2.19-8.08) were more likely to have a positive attitude toward benefits of exercise during pregnancy.ConclusionThe level of mothers' knowledge and attitude toward exercise during pregnancy in the study area was low. Educational status, physical exercise before pregnancy, ever heard about exercise during pregnancy were independent determinants of women's knowledge, while ever heard and knowledgeable about exercise during pregnancy were determinants of favorable attitude toward exercise during pregnancy. Empowering women through health education about physical exercise during pregnancy should get due attention.

Project description:Anemia is a major cause of morbidity and mortality of pregnant women and increases the risks of fetal and neonatal morbidity and mortality. Approximately 50% of all anemia is estimated to be caused by low dietary intake of iron, poor absorption of dietary iron, or blood loss. The objective of the present study was to determine the prevalence of and assess the dietary habits associated with anemia in pregnant women receiving antenatal care (ANC) in Unguja Island, Tanzania. A cross-sectional study was conducted to select 338 pregnant women at Kivunge, Mwembeladu, and Mnazimmoja hospitals from March to June 2018. Hemoglobin concentration was measured using a HemoCue photometer on capillary blood. Sociodemographic data and dietary habits were collected using a structured questionnaire. Multivariate logistic regression analysis was carried out to determine the predictors of anemia in pregnant women. The overall prevalence of anemia was 80.8%. Of these 68.64% had mild anemia, 11.24% had moderate anemia, and 0.89% had severe anemia. Anemia was significantly associated with inadequate dietary diversity [adjusted OR (AOR): 1.16; 95% CI: 0.57, 2.36; P < 0.05], drinking tea or coffee with a meal (AOR: 0.06; 95% CI: 0.03, 0.13; P < 0.001), consuming <3 meals/d (AOR: 2.92; 95% CI: 1.60, 5.84; P < 0.001), higher education level (AOR: 3.4; 95% CI: 1.6, 7.2; P < 0.0001), birth interval <2 y (AOR: 3.6; 95% CI: 1.1, 11.9; P < 0.05), and multigravida status (AOR: 1.2; 95% CI: 0.3, 4.4; P < 0.0001). The prevalence of anemia in this study demonstrates a severe public health problem among pregnant women. Inadequate dietary diversity coupled with inadequate daily meal intake and consumption of tea or coffee were the dietary habits predicting anemia in pregnant women. Other predictors of anemia were higher education level, multigravida status, and birth interval <2 y. Nutrition policy interventions are needed to complement ANC services by providing important information on healthy eating habits during pregnancy.

Project description:BackgroundThe purpose of antenatal care is to monitor and improve the wellbeing of the mother and foetus. The World Health Organization recommends risk-oriented strategy that includes: (i) routine care to all women, (ii) additional care for women with moderately severe diseases and complications, (iii) specialised obstetrical and neonatal care for women with severe diseases and complications. Antenatal care is concerned with adequate care in order to be effective. Measurement for adequacy of antenatal care often applies indexes that assess initiation of care and number of visits. In addition, adequacy of care content should also be assessed. Results of studies in developed settings demonstrate that women without risk factors use antenatal services more frequently than recommended. Such over-utilisation is problematic for low-resourced settings. Moreover, studies show that a substantial proportion of high-risk women had utilisation or content of care below the recommended standard. Yet studies in developing countries have seldom included a comparison between low-risk and high-risk women. The purpose of the study was therefore to assess adequacy of care and pregnancy outcomes for the different risk groups.MethodsA retrospective study using a multistage sampling technique, at public-funded primary health care clinics was conducted. Antenatal utilisation level was assessed using a modified Adequacy of Prenatal Care Utilisation index that measures the timing for initiation of care and observed-to-expected visits ratio. Adequacy of antenatal care content assessed compliance to routine care based on the local guidelines.ResultsIntensive or "adequate-plus" antenatal care utilisation as defined by the modified index was noted in over half of the low-risk women. On the other hand, there were 26% of the high-risk women without the expected intensive utilisation. Primary- or non-educated high-risk women were less likely to have a higher antenatal care utilisation level compared with tertiary educated ones (OR = 0.20, P = 0.003). Half of all women had <80% of the recommended antenatal care content. A higher proportion of high-risk than low-risk women scored <80% of the routine care content (p<0.015). The majority of the additional laboratory tests were performed on high-risk women. Provision of antenatal education showed comparatively poor compliance to guidelines, more than half of the antenatal advice topics assessed were rarely provided to the women. High-risk women were associated with a higher prevalence of adverse pregnancy outcome.ConclusionsDisproportionate utilisation of antenatal care according to risk level of pregnancy indicates the need for better scheduling of care. The risk-oriented approach often results in a tendency to focus on the risk conditions of the women. Training interventions are recommended to improve communication and to help healthcare professionals understand the priorities of the women. Further studies are required to assess the reason for disproportionate utilisation of antenatal care according to risk level and how delivery of antenatal advice can be improved, reviewing both user and provider perspectives.

Project description:BackgroundUptake and retention in antenatal care (ANC) is critical for preventing adverse pregnancy outcomes for both mothers and infants.MethodsWe implemented a rapid quality improvement project to improve ANC retention at seven health facilities in Eswatini (October-December 2017). All pregnant women attending ANC visits were eligible to participate in anonymous tablet-based audio assisted computer self-interview (ACASI) surveys. The 24-question survey asked about women's interactions with health facility staff (HFS) (nurses, mentor mothers, receptionists and lab workers) with a three-level symbolic response options (agree/happy, neutral, disagree/sad). Women were asked to self-report HIV status. Survey results were shared with HFS at monthly quality improvement sessions. Chi-square tests were used to assess differences in responses between months one and three, and between HIV-positive and negative women. Routine medical record data were used to compare retention among pregnant women newly enrolled in ANC two periods, January-February 2017 ('pre-period') and January-February 2018 ('post-period') at two of the participating health facilities. Proportions of women retained at 3 and 6 months were compared using Cochran-Mantel-Haenszel and Wilcoxon tests.ResultsA total of 1,483 surveys were completed by pregnant women attending ANC, of whom 508 (34.3%) self-reported to be HIV-positive. The only significant change in responses from month one to three was whether nurses listened with agreement increasing from 88.3% to 94.8% (p<0.01). Overall, WLHIV had significantly higher proportions of reported satisfaction with HFS interactions compared to HIV-negative women. A total of 680 pregnant women were included in the retention analysis; 454 (66.8%) HIV-negative and 226 (33.2%) WLHIV. In the pre- and post-periods, 59.4% and 64.6%, respectively, attended at least four ANC visits (p = 0.16). The proportion of women retained at six months increased from 60.9% in the pre-period to 72.7% in the post-period (p = 0.03). For HIV-negative women, pre- and post-period six-month retention significantly increased from 56.6% to 71.6% (p = 0.02); however, the increase in WLHIV retained at six months from 70.7% (pre-period) to 75.0% (post-period) was not statistically significant (p = 0.64).ConclusionThe type of rapid quality improvement intervention we implemented may be useful in improving patient-provider relationships although whether it can improve retention remains unclear.
