Compliance to iron supplementation during pregnancy

Factors associated with anaemia in pregnancy: A retrospective cross-sectional study in the Bolgatanga Municipality, northern Ghana

BACKGROUND

Anaemia in pregnancy (AIP) remains a severe public health problem associated with adverse outcomes. This study assessed haemoglobin levels and the prevalence of anaemia during antenatal care (ANC) registration, at 28 weeks and 36 weeks of gestation as well as the factors associated with AIP at the different stages of pregnancy.

METHODS

A retrospective cross-sectional design was implemented. Using ANC registers as the sampling frame, 372 pregnant women, within 36 and 40 weeks of gestation were randomly sampled from 28 health facilities for the study. The participants were all receiving ANC in the Bolgatanga Municipality. Data were collected via clinical records review and a questionnaire-based survey between October and November, 2020. Using the Statistical Package for the Social Sciences (SPSS), descriptive analysis of haemoglobin levels and the prevalence of anaemia were performed. In addition, binary logistic regression was used to identify the factors associated with anaemia in pregnancy. AIP was determined using the national practice of 11.0g/dl haemoglobin cut-off point and the World Health Organisation's recommended adjustment for the 2nd trimester of pregnancy was made using the cut-off of 10.5g/dl to account for the effect of haemodilution.

RESULTS

At booking, AIP prevalence was 35.8% (95%CI:30.9, 40.9) using a cut-off of 11.0g/dl and 25.3% (95%CI:20.9, 30.0) using a cut-off of 10.5g/dl for those in the 2nd trimester. At 28 weeks, AIP prevalence was 53.1% (95%CI:45.8, 60.3) and 37.5 (95%CI:30.6, 44.8) using a cut-off of 11.0g/dl and 10.5g/dl for those in the 2nd trimester, respectively. At 36 weeks, AIP prevalence was 44.8% (95%CI:39.2, 50.4) using a cut-off of 11.0g/dl. At p<0.05, registering after the first trimester (AOR = 1.87, 95%CI: 1.17, 2.98, P = 0.009) and at a regional hospital (AOR = 2.25, 95%CI: 1.02, 4.98, P = 0.044) were associated with increased odds of AIP but registering at a private hospital (AOR = 0.32, 95%CI: 0.11, 0.92, P = 0.035) was associated with decreased odds of AIP at booking. At 28 weeks, age group 26-35 years (AOR = 0.46, 95%CI: 0.21, 0.98, P = 0.044), Christianity (AOR = 0.32, 95%CI: 0.31, 0.89, P = 0.028.), high wealth (AOR = 0.27, 95%CI: 0.09, 0.83, P = 0.022) and tertiary education (AOR = 0.09, 95%CI:0.02, 0.54, P = 0.009) were associated with decreased odds of AIP. At 36 weeks, booking after first trimester of pregnancy was associated with increased odds (AOR = 1.72, 95%CI: 1.05, 2.84, P = 0.033) whilst high wealth (AOR = 0.44, 95%CI: 0.20, 0.99, P = 0.049), higher age groups-26-35 (AOR = 0.38, 95%CI: 0.21, 0.68, P = 0.001) and 36-49 years (AOR = 0.35, 95%CI: 0.13, 0.90, P = 0.024) and secondary education of spouse were associated with reduced odds (AOR = 0.35, 95%CI: 0.14, 0.88, P = 0.026) of AIP.

CONCLUSION

AIP consistently increased from registration to 36 weeks of gestation. Given the observed correlates of AIP, we recommend that interventions geared towards early ANC registration, improved household wealth, and improved maternal education are required to reduce AIP.

Compliance compromises an interventional study on iron supplementation in female combatants

INTRODUCTION

Low iron levels are related to overuse injuries, poor physical performance and cognitive impairments in female recruits. The aim of this study was to evaluate iron supplement compliance in female combatants during basic training, and its effect on haemoglobin (Hgb), ferritin and injuries.

METHODS

329 female recruits to light infantry units filled induction questionnaires regarding smoking status, previous overuse injuries and iron deficiency. Blood was drawn for Hgb and ferritin. Subjects with ferritin levels below 20 ng/mL were considered iron depleted and were prescribed a ferrous fumarate supplement. After 4 months of basic training, the subjects completed a follow-up questionnaire regarding overuse injuries, reasons for failure to complete basic training and compliance with iron supplementation. Blood tests were repeated.

RESULTS

Mean ferritin levels declined during training (from 18.1±18.2 to 15.3±9.6, p=0.01). Compliance with iron supplementation was observed in 26 (26.3%) of the subjects. In compliant subjects, Hgb levels remained constant and ferritin levels increased by 2.9±5.4 (p=0.07). The main reasons for reported non-compliance were forgetfulness, 26 (35.6%), and gastrointestinal side effects, 17 (23.3%). Injuries during training were not found to be associated with iron status. Smokers had a significantly higher rate of reported injuries prior to training (p<0.01).

CONCLUSIONS

Ferritin levels decline during training. Compliance with iron supplementation is low. Iron supplementation has a significant effect on ferritin levels, even in the non-compliance group. Injuries were not related to iron status in this group. Further research is needed in order to clarify the most appropriate iron supplementation method.

Effect of Mobile Phone Call Reminders With Standard Therapy Versus Standard Therapy Alone on Compliance With Iron Supplementation in Antenatal Women With Iron Deficiency Anemia: A Randomized Controlled Trial

Introduction

In spite of the implementation of the National nutritional anemia prophylaxis program in India, the prevalence of anemia during pregnancy is 50 in 100 women. One main cause for the high frequency of anemia among antenatal women in India is a lack of iron consumption. Few studies are available in the literature where efforts have been made to improve compliance with iron therapy. In the same line of thinking, it was decided in the present study to use mobile phone calls as a reminder for iron tablets.

Method

The present study is a randomized controlled open-label trial. Antenatal women with gestational age between 13-28 weeks of pregnancy diagnosed with iron deficiency anemia (Hb - 8 to 11 gm/dl) having mobile phones were included in the study. Recruited women were randomized into two groups of study groups receiving standard therapy with the addition of fortnightly mobile phone call reminders and a control group receiving standard therapy alone.

Results

Compliance with iron supplementation was observed higher in the study group as compared to the control group (range of 48% to 93%). There was a mean hemoglobin rise in both the groups at the time of delivery compared with the hemoglobin at the time of recruitment (Study group- 9.74 to 10.69, Control group- 9.48 to 10.06). There was a statistically higher (0.00001) increase in the mean hemoglobin concentration in the study group (0.96 gm/dl) as compared to the control group (0.59 gm/dl). The reasons for poor compliance were boredom with taking daily oral iron therapy (66.66%), constipation (3.7%), forgetfulness (14.81%), and heartburn (14.81%). There was no statistical difference in the reason for poor compliance with iron supplementation in both groups.

Conclusion

The present study concludes that mobile phone call reminders along with standard therapy with iron supplementation improve compliance with iron supplementation and lead to a greater rise in hemoglobin in antenatal women with iron deficiency anemia.

Effectiveness of Health Information Package Program on Knowledge and Compliance among Pregnant Women with Anemia: A Randomized Controlled Trial

Despite the availability of iron supplements during pregnancy for all pregnant women receiving antenatal care in Saudi Arabia, anemia remains to be a global public health concern leading to adverse maternal, fetal, and neonatal effects. We aimed to evaluate the effectiveness of the Health Information Package Program on the knowledge anemic pregnant women had about anemia, their compliance with iron and folic acid supplementation, and their hemoglobin levels. A single-blind randomized controlled trial was carried out in accordance with the Consolidated Standards of Reporting Trials (CONSORT) guidelines between January and May 2021. Pregnant women (n = 196) aged 18–45 years old and diagnosed with anemia during the first trimester of their pregnancy were randomly assigned into two groups: the intervention group (Health Information Package Program plus routine care, n = 98) and the control group (routine care only, n = 98). Knowledge, the ability to select appropriate food, and hemoglobin levels were assessed at baseline and after three months, while compliance with iron and folic acid supplementation was also measured at the end of three months. This study indicated that the post-education mean knowledge score, food selection ability score, compliance rate, and hemoglobin level were significantly higher for the intervention group than for the control group. The Health Information Package Program with regular follow-ups using the WhatsApp platform was an effective educational intervention for anemic pregnant women.

Prevalence of Anemia and Associated Risk Factors Among Non-Pregnant Women in Riyadh, Saudi Arabia: A Cross-Sectional Study

BACKGROUND

Iron deficiency is known to be the most common nutritional disorder. About 30% of the world's population is iron deficient (ID). Women are more likely to be exposed to anemia than men, which is an epidemic public health problem.

OBJECTIVE

A cross-sectional study was carried out to investigate the prevalence of anemia and associated risk factors among non-pregnant women in Riyadh, Saudi Arabia.

METHODS

Non-pregnant women (n = 250) aged 20-65 years were involved in this study. Sociodemographic, nutritional status, menstrual history, anthropometric and haematological properties were calculated. Anaemia proxies including haemoglobin (HB), serum ferritin (IDA), Haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were determined as well as BMI.

RESULTS

The respondents were varied according to demographic factors and according to anemia proxies, the majority of them suffered from anemia. The Student's t-test analysis showed that the average daily food intake was lower than that of the dietary requirement intake (DRI). Correlation and logistic regression analysis between sociodemographic factors and anemia proxies revealed that most of such factors significantly and negatively affected anemia proxies. Moreover, the correlation of daily food intake and anemia proxies showed that the nutrients responsible for the improvement of anemia proxies were not taken in sufficient amount as indicated by a significant and positive correlation.

CONCLUSION

In conclusion, various factors including demographic factors, daily food intake appeared to be associated with anemia proxies, which are the most important risk factor for anemia among non-pregnant women in Riyadh, Saudi Arabia.

Consensus Statement by an Expert Panel on the Diagnosis and Management of Iron Deficiency Anemia in the Gulf Cooperation Council Countries

BACKGROUND

Iron deficiency (ID) and ID anemia (IDA) are common in the member states of the Gulf Cooperation Council (GCC). The unique genetic and lifestyle factors of the patient population in the region have necessitated the development of recommendations to help educate health-care professionals on appropriate diagnosis and management of ID/IDA.

METHODS

A panel of regional experts, including gastroenterologists and hematologists with expertise in the treatment of IDA, was convened to develop regional practice recommendations for ID/IDA. After reviewing the regional and international literature, the expert panel developed consensus recommendations for screening, diagnosis, and treatment of patients with IDA in the GCC region.

RESULTS

The recommendations proposed were customized to the patient population keeping in view the increasingly recognized burden of coeliac disease, high fertility and obesity rates, high prevalence of alpha- and beta-thalassemia traits, and poor tolerance and low treatment compliance with oral iron therapy.

CONCLUSIONS

This consensus statement proposes recommendations for screening, diagnosis, and treatment of IDA in the GCC region.

Assessment of adherence to iron supplementation among pregnant women in the Yaounde gynaeco-obstetric and paediatric hospital

Introduction

Anemia is a global problem affecting 41.8% of pregnant women. Iron deficiency is the leading cause during pregnancy. Its prevalence among Cameroonian pregnant women was estimated at 50.9% in 2004. Few studies have evaluated women's adherence to iron supplementation prescribed during pregnancy. We carried this study in order to evaluate the rate of adherence to iron supplementation and its determinants during pregnancy.

Methods

The study was cross-sectional descriptive, on postpartum women at the Gynaeco-Obstetric and Pediatric Hospital of Yaoundé during three months. Adherence was measured using the 8-item Morisky Medication Adherence Scale (MMAS-8). The total score was classified as low, moderate and high adherence.

Results

For a total of 304 recruited women, 16.4% were highly compliant, 27.6% moderately compliant, while 56% were low compliant with iron supplementation during pregnancy. The reasons for non-adherence were side effects (19.7%), forgetting (70.1%) and inaccessibility of iron supplements (20.1%). Up to 85 (or 28%) women found it boring to take medication daily. Women with no side effects were about thrice most likely to adhere to the iron supplementation than those with side effects: OR = 3.73 [2.43-5.71]; P = 0.04. Women aged 25 years and above were more likely to be non-compliant to iron supplementation than those youngers: OR = 0.40 [0.31-0.88]; P = 0.02.

Conclusion

To improve adherence to antenatal iron supplementation, it is important to increase communication for behavior change and counseling before or during antenatal care. Forgetting being the main reason for non-adherence, women should keep their iron in a place of easy access.

Prevalence and determinants of anaemia in pregnant women receiving antenatal care at a tertiary referral hospital in Northern Ghana

Background

Anaemia during pregnancy is a major public health problem in developing countries. It is important to regularly monitor haemoglobin level in pregnancy and factors associated with it to inform clinical and preventive services. The aim of this study was to assess the prevalence and determinants of anaemia in pregnant women attending antenatal clinic (ANC) of a tertiary referral hospital in Northern Ghana.

Methods

An analytical cross-sectional study involving 400 pregnant women receiving antenatal care in Tamale Teaching Hospital was conducted. Using a semi-structured questionnaire and 24-h dietary recall, data were collected on socio-demographic characteristics, health practices, dietary diversity, anaemia knowledge and haemoglobin level of the women. Anaemia was defined as haemoglobin concentration less than 11 g/dl. Chi-square test and logistic regression analysis were used to identify the independent determinants of pregnancy anaemia.

Results

The mean age and haemoglobin of the women were 28.3 (±4.5) years and 10.81 (±1.41) g/dl respectively. About half of the women 50.8% [95% Confidence Interval (CI): 45.8–55.7] were anaemic and the prevalence of anaemia increased with pregnancy trimester. Among a host of socio-demographic, dietary, and preventive health service factors evaluated, the women’s knowledge on anaemia and pregnancy trimester at interview were the independent determinants of anaemia in pregnancy. Compared to women of the highest anaemia knowledge tertile, women belonging to the lowest (AOR = 2.63, 95% CI: 1.50–4.61) and middle (AOR = 1.92, 95% CI: 1.12–3.27) anaemia knowledge tertiles were about 3 and 2 times more likely to be anaemic respectively. Similarly, women in third trimester of pregnancy were about 4 times more likely to be anaemic compared to those in first trimester at the time of interview (AOR = 3.57, 95% CI: 1.91–6.67).

Conclusions

There is a high prevalence of anaemia, which increases with pregnancy trimester, in pregnant women attending ANC in a tertiary referral hospital in Northern Ghana. The women’s knowledge on anaemia and pregnancy trimester at the time of interview are associated with their anaemia status. The high prevalence of anaemia in pregnancy needs urgent intervention to prevent the occurrence of adverse maternal and neonatal outcomes. Education on anaemia should be intensified at ANCs.

Adherence to Iron Supplementation in 22 Sub-Saharan African Countries and Associated Factors among Pregnant Women: A Large Population-Based Study

BACKGROUND

Iron deficiency anemia during pregnancy is a significant public health problem in sub-Saharan Africa (SSA) and is associated with serious adverse health outcomes. Although it is recommended that all women receive iron supplementation during pregnancy, little research has been conducted to measure overall compliance with this recommendation or variation across SSA countries.

OBJECTIVES

To assess prevalence and sociodemographic-economic factors associated with adherence to iron supplementation among pregnant women in SSA.

METHODS

This was a weighted population-based cross-sectional study of 148,528 pregnant women aged 15-49 y in 22 SSA countries that participated in the Demographic and Health Surveys (DHS) in 2013-2018 and measured iron supplementation during pregnancy. Adherence to iron supplementation was defined as using iron supplementation for ≥90 d during pregnancy of the most recent birth.

RESULTS

The overall prevalence of adherence to ≥90 d of iron supplementation during pregnancy was 28.7%, ranging from 1.4% in Burundi to 73.0% in Senegal. Factors associated with adherence included receiving ≥4 antenatal care visits [adjusted Prevalence Ratio (aPR): 25.73; 95% CI: 22.36, 29.60] compared with no antenatal visits; secondary or higher education (aPR: 1.17; 95% CI: 1.14, 1.19) compared with no education; wealthy (aPR: 1.13; 95% CI: 1.10, 1.16) compared with poor; and older women aged 35-49 y (aPR: 1.07; 95% CI: 1.05, 1.10) compared with younger women aged 15-24 y.

CONCLUSIONS

Adherence to iron supplementation during pregnancy in SSA is low and varies substantially across countries and in relation to factors such as number of antenatal visits, education, and level of family wealth. These results underscore the need for increased efforts to improve the uptake of iron supplementation for pregnant women in SSA.

Better-Educated, Older, or Unmarried Pregnant Women Comply Less with Iron-Folic Acid Supplementation in Southern Ethiopia

Daily iron supplementation, with or without folic acid, is a proven public health intervention. Although maintaining compliance is crucial for the success of the intervention, inconsistent findings are available on compliance and its predictors in Ethiopia. The aim of this study was to estimate the iron-folic acid (IFA) supplementation compliance rate and its predictors among pregnant women in Wolaita Zone, Southern Ethiopia. A cross-sectional study was conducted in eight randomly selected health centers in Wolaita, Southern Ethiopia. A total of 647 pregnant women were included using multistage sampling procedure. Data were entered into Epi Info (a free statistical analysis software) and exported to SPSS. Bivariate relationship was explored through correlation coefficients. A multiple linear regression model was constructed to estimate the variability coefficient of the compliance rate due to selected factors. Of 647 pregnant women, only 18 (2.8%) pregnant women had received the supplement for 90 days or more. Overall, the compliance rate was 73.2% (95% CI, 70.72 to 75.79). Experiencing heartburn and vomiting significantly reduced the compliance rate. Unintended pregnancy and better education were negatively associated with compliance. By contrast, acceptability of IFA supplement, number of antenatal care (ANC) visits, and being ever married were positive predictors. On average, a pregnant woman did not take more than one-fourth of the daily IFA supplementation. During ANC visits, addressing the issues of side effects, unintended pregnancy, and acceptability of the supplement may improve compliance rate. Overall in Ethiopia, educated, older, and unmarried Ethiopian women need additional attention for successful compliance.

Preventing complications by persistence with iron replacement therapy: a comprehensive literature review

OBJECTIVE

Iron deficiency and particularly iron deficiency anemia (IDA) can lead to negative health consequences. This review describes the importance of adherence and persistence (adhering to treatment for the recommended duration) with iron replacement therapy in the prevention of complications, particularly regarding its recommended dosing schedule.

METHODS

Comprehensive literature searches were performed of Medline and the Cochrane library from 2000 to 2018. Keywords included iron deficiency or IDA, compliance or adherence, persistence, health beliefs, risk factor, complications, dosing cycles, oral iron replacement therapy and recommendations for duration, ferrous compounds, iron supplementation, dietary iron, and delayed-action/slow-release preparations.

RESULTS

Identified articles focused on IDA as a risk factor (particularly for worsened comorbidities or surgical outcomes), guidelines, adherence and persistence, and differences between iron formulations. Current guidelines and expert opinion continue to support oral iron supplementation as first-line therapy. While it is recommended to take iron therapy for 2 months to normalize hemoglobin, then 2-3 months to build up iron stores, many patients face difficulties in adhering to and persisting with the full iron treatment regimen. Patient education and understanding, social support, simple dosing, perceived efficacy including reduced symptoms and tolerability were factors noted to promote medication adherence and persistence. Adherence to iron therapies appears to be facilitated by using ferrous sulfate due to its optimal absorption, and particularly extended-release forms due to their improved tolerability for iron deficiency.

CONCLUSIONS

Proper adherence and persistence with iron supplementation may prevent or reduce the risk of complications of iron deficiency and IDA.

Compliance of iron and folic acid supplementation and status of anaemia during pregnancy in the Eastern Terai of Nepal: findings from hospital based cross sectional study

Objectives

Our study aimed to assess local data for compliance with IFA supplementation and prevalence of anaemia among the pregnant mothers visiting government health facilities of eastern Nepal.

Results

In our study samples, IFA compliance rate was 58% during pregnancy and 42% were anaemic. Anemia was 24 times more likely to occur in IFA noncompliant women during pregnancy than their counterparts (aOR = 24.2, 95% CI 10.1–58.3), and anemia was three times less likely to be found in those taking foods rich in heme–iron than their counterparts (aOR = 3.3, 95% CI 1.4–8.1).

Parenteral Versus Oral Iron for Treatment of Iron Deficiency Anaemia During Pregnancy and post-partum: A Systematic Review

Introduction

The burden of iron deficiency anaemia during pregnancy and post-partum continues to remain high especially in India. Challenges to treatment include gastrointestinal side effects and non compliance to oral iron therapy. Newer parenteral formulations need to be explored as alternatives.

Methods

Meta-analysis of randomized controlled trials published between years 2011 and 2018 comparing anaemic pregnant and post-partum women treated with intravenous iron sucrose versus oral iron was performed. The primary outcomes were mean maternal haemoglobin, serum ferritin and haematocrit at the end of 1st, 2nd, 4th and 6th weeks and comparison of adverse effects.

Results

Eighteen studies including 1633 antenatal women were randomly assigned to intravenous iron sucrose (n = 821) or oral iron [ferrous sulphate, ferrous ascorbate or fumarate] group (n = 812) in ten trials . Another eight studies compared iron sucrose infusion with oral iron in 713 post-partum women who were randomly assigned to intravenous iron sucrose group (n = 351) or oral iron group (n = 362). Cumulative analysis of all the time points indicates that the estimated mean values of Hb in the intravenous iron sucrose and oral iron groups were 10.11 g/dl and 9.33 g/dl, respectively, in antenatal group, while it was 10.57 g/dl and 9.74 g/dl in post-partum. The estimated mean ferritin level from first week to six weeks was 63.1 μg/l and 28.6 μg/l, respectively, in intravenous and oral iron groups. Cumulative estimate of haematocrit in the intravenous sucrose and oral iron over 6 weeks showed that the mean values in the respective groups were 30.5% and 29.5% in antenatal and 33.8% and 31.6%, respectively, in post-partum groups. Sensitivity analysis confirmed the reliability and consistency of the results. Oral iron was associated with significant gastrointestinal side effects. There was no significant difference in birthweight between the groups.

Conclusion

This meta-analysis demonstrates that intravenous iron sucrose is more effective than oral iron therapy for pregnant and post-partum women with iron deficiency anaemia. It is an effective and safe alternative to address the problem of iron deficiency especially in those who require rapid replacement of iron stores though medical personnel for intravenous administration of drug is required.Trial registration CRD42015024343.

The impact of a planned health educational program on the compliance and knowledge of Jordanian pregnant women with anemia

Iron deficiency anemia is a major public health problem among pregnant women in developing countries. This study aimed to use a randomized controlled trial to evaluate the effectiveness of a health information package in Jordanian anemic pregnant women's knowledge regarding anemia, compliance with iron supplementation, and hemoglobin level. Two hundred pregnant anemic women were recruited and randomly assigned into intervention or control group from April to July 2016. The intervention group received a video presentation of the Health Information Package Program (HIPP), narrated by a midwife, combined with PowerPoint slides to educate women about anemia in pregnancy. The participants in the control group received standard care in antenatal clinics, including iron supplementation. No significant differences were observed between the groups in age, gestational age, health problems, and total income. Only education and source of information differed significantly between the groups. Women in the intervention group had higher scores on the compliance checklist, knowledge, food selection ability, and hemoglobin level than women in the control group. The health information package program was effective. Policymakers should adopt a health information package program and apply it as a comprehensive national strategy for the prevention of anemia during pregnancy.

Prevalence of Anemia and Iron Deficiency among Palestinian Pregnant Women and Its Association with Pregnancy Outcome

BACKGROUND

Anemia is a public health problem especially among pregnant women. This study aimed to investigate the prevalence of anemia and iron deficiency among pregnant women and its association with pregnancy outcome in Hebron Governorate in southern Palestine.

METHODS

This is a cross-sectional study that included 300 pregnant women in their first trimester and 163 babies. Maternal anthropometric and socioeconomic and newborns' data were collected. Complete blood count for study subjects and maternal serum ferritin were measured.

RESULTS

The prevalence of iron deficiency anemia among pregnant women was 25.7% and 52% of them had depleted iron stores. When pregnant women were grouped into three hemoglobin (Hb) tertile groups, a significant difference was observed between maternal Hb and newborns' birth weight (P= 0.009), height (P= 0.022), head circumference (P= 0.017), and gestational age (P= 0.012). There was a significant association between maternal serum ferritin and frequency of low birth weight (P= 0.001) and frequency of preterm delivery (P= 0.003). No significant association was observed between maternal anthropometric measures or the socioeconomic status and pregnancy outcomes.

CONCLUSION

Iron deficiency is a moderate public health problem among the study subjects. Maternal Hb and serum ferritin significantly affect pregnancy outcomes.

Women's Awareness and Associated Factors on Preconception Folic Acid Supplementation in Adet, Northwestern Ethiopia, 2016: Implication of Reproductive Health

Introduction

Preconception folic acid supplementation is the provision of folate for reproductive age group women who have a plan to be pregnant. According to different studies, in African countries, there is poor utilization of preconception folic supplementation. So this study aimed at assessing women's awareness on preconception care and its associated factors in Adet, Northwestern Ethiopia.

Methods

A community-based cross-sectional study was conducted from March 1 to April 1, 2016, among 422 reproductive age group women. Systematic random sampling was used to get the study unit, and the data were collected using pretested structured questionnaire via face-to-face interview. The collected data were entered, cleaned, checked using EpiData version 3.1, and finally analyzed using SPSS version 20. Descriptive summary of the data was presented in terms of percentage and frequency. Binary and multiple logistic regressions were used in order to identify predictors using odds ratio at 95% confidence interval.

Result

In this study, a total of 422 reproductive age group women participated with a response rate of 100%. Of a total of 422 participants, 67 (15.9%) of the women had good awareness on preconception folic acid supplementation. Women's awareness on preconception folic acid supplementation was affected by having a chronic health problem, monthly household income, educational status, and a history of family planning use. Women who were educated (AOR 4.77, CI 1.85-6.98), had a history of family planning use (AOR 3.89, CI 1.77-8.55), had a chronic health problem (AOR 3.47, CI 2.68-5.98), and had a better monthly income (AOR 2.6, CI 2.05-6.76) had good awareness than their counterparts.

Conclusion and Recommendation

This study concluded that women's awareness on preconception folic acid supplementation was low. This finding suggests that there is a need to give emphasis and deliver health education about preconception folic acid supplementation for women.

The Impact of Traditional Food and Lifestyle Behavior on Epigenetic Burden of Chronic Disease

Noncommunicable chronic diseases (NCCDs) are the leading causes of morbidity and mortality globally. The mismatch between present day diets and ancestral genome is suggested to contribute to the NCCDs burden, which is promoted by traditional risk factors like unhealthy diets, physical inactivity, alcohol and tobacco. However, epigenetic evidence now suggests that cumulatively inherited epigenetic modifications may have made humans more prone to the effects of present day lifestyle factors. Perinatal starvation was widespread in the 19th century. This together with more recent events like increasing consumption of western and low fiber diets, smoking, harmful use of alcohol, physical inactivity, and environmental pollutants may have programed the human epigenome for higher NCCDs risk. In this review, on the basis of available epigenetic data it is hypothesized that transgenerational effects of lifestyle factors may be contributing to the current global burden of NCCDs. Thus, there is a need to reconsider prevention strategies so that the subsequent generations will not have to pay for our sins and those of our ancestors.

Adherence to iron supplements among women receiving antenatal care at Mulago National Referral Hospital, Uganda-cross-sectional study

Background

Antenatal iron supplementation is a cost effective way of reducing iron deficiency anaemia among pregnant women in resource limited countries like Uganda. Poor adherence to iron supplements has limited its effectiveness in reducing maternal anaemia as evidenced by the high burden of iron deficiency anemia in Sub-saharan Africa. The aim of this study was to determine the level of and factors associated with adherence to iron supplementation among women attending antenatal clinic at Mulago National Referral Hospital, Kampala, Uganda.

Methods

Three hundred and seventy pregnant women were recruited in a cross sectional survey in Mulago National Referral Hospital antenatal clinic after informed consent between February and April 2014. Levels of adherence to iron supplements were assessed using visual analogue scale and factors associated collected using an interviewer administered questionnaire.

Results

About 12% (11.6%) of the mothers attending the antenatal clinic adhered to iron supplements over 30 day period. Mothers who had had four or more antenatal visits prior to the survey [odds ratio (OR) = 1.49, 95% confidence interval (CI) 1.12–1.97], had more than 2 week supply of iron supplements in the previous visit (OR 2.81, 95% CI 1.02–1.09), prior health education (OR 1.56, 95% CI 1.07–2.29) were more likely to adhere to iron supplements. Inadequate drug supplies and fear for side effects were the main reasons why participants missed the iron supplements.

Conclusions

There was low adherence to iron supplements among mothers attending antenatal clinic at Mulago National Referral  Hospital. We recommend a national evaluation of adherence to iron supplements and look at ways of increasing adherence.

Rankings of iron, vitamin D, and calcium intakes in relation to maternal characteristics of pregnant Canadian women

Iron, vitamin D, and calcium intakes in the prenatal period are important determinants of maternal and fetal health. The objective of this study was to examine iron, vitamin D, and calcium intakes from diet and supplements in relation to maternal characteristics. Data were collected in a subsample of 1186 pregnant women from the Maternal-Infant Research on Environmental Chemicals (MIREC) Study, a cohort study including pregnant women recruited from 10 Canadian sites between 2008 and 2011. A food frequency questionnaire was administered to obtain rankings of iron, calcium, and vitamin D intake (16-21 weeks of pregnancy). Intakes from supplements were obtained from a separate questionnaire (6-13 weeks of pregnancy). Women were divided into 2 groups according to the median total intake of each nutrient. Supplement intake was an important contributor to total iron intake (median 74%, interquartile range (IQR) 0%-81%) and total vitamin D intake (median 60%, IQR 0%-73%), while the opposite was observed for calcium (median 18%, IQR 0%-27%). Being born outside of Canada was significantly associated with lower total intakes of iron, vitamin D, and calcium (p ≤ 0.01 for all). Consistent positive indicators of supplement use (iron, vitamin D, and calcium) were maternal age over 30 years and holding a university degree. In conclusion, among Canadian women, the probability of having lower iron, vitamin D, and calcium intakes is higher among those born outside Canada; supplement intake is a major contributor to total iron and vitamin D intakes; and higher education level and age over 30 years are associated with supplement intake.

Ferrous sulfate supplementation causes significant gastrointestinal side-effects in adults: a systematic review and meta-analysis

Background

The tolerability of oral iron supplementation for the treatment of iron deficiency anemia is disputed.

Objective

Our aim was to quantify the odds of GI side-effects in adults related to current gold standard oral iron therapy, namely ferrous sulfate.

Methods

Systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating GI side-effects that included ferrous sulfate and a comparator that was either placebo or intravenous (IV) iron. Random effects meta-analysis modelling was undertaken and study heterogeneity was summarised using I² statistics.

Results

Forty three trials comprising 6831 adult participants were included. Twenty trials (n = 3168) had a placebo arm and twenty three trials (n = 3663) had an active comparator arm of IV iron. Ferrous sulfate supplementation significantly increased risk of GI side-effects versus placebo with an odds ratio (OR) of 2.32 [95% CI 1.74–3.08, p<0.0001, I² = 53.6%] and versus IV iron with an OR of 3.05 [95% CI 2.07-4.48, p<0.0001, I² = 41.6%]. Subgroup analysis in IBD patients showed a similar effect versus IV iron (OR = 3.14, 95% CI 1.34-7.36, p = 0.008, I² = 0%). Likewise, subgroup analysis of pooled data from 7 RCTs in pregnant women (n = 1028) showed a statistically significant increased risk of GI side-effects for ferrous sulfate although there was marked heterogeneity in the data (OR = 3.33, 95% CI 1.19-9.28, p = 0.02, I² = 66.1%). Meta-regression did not provide significant evidence of an association between the study OR and the iron dose.

Conclusions

Our meta-analysis confirms that ferrous sulfate is associated with a significant increase in gastrointestinal-specific side-effects but does not find a relationship with dose.

Process evaluation of a national school-based iron supplementation program for adolescent girls in Iran

Background

Iron deficiency anemia remains as one of the most common nutritional problems in Iran, especially in women and girls. A process evaluation study of the national iron supplementation program targeting girls attending high schools was conducted to examine degree of exposure and satisfaction of the targets with the intervention components, and to assess the delivery (quantity), fidelity (quality), and environmental mediators of the intervention.

Methods

Three assessment tools were developed and used for the process evaluation. A total of 8 schools were selected using a simple randomization method. Data were collected from students (n = 658 of 661 participants), teachers (n = 80), and school principals (n = 7 of 8). For the qualitative measures semi-structured interviews were conducted with the three study groups.

Results

Mean continuous compliance was 62.3%. Intolerance to pills and no water supply in classrooms accounted for 47.72% and 36.21% of the refusals, respectively. The refusal rate was significantly correlated (p < 0.001) with the absence of a classroom water supply, and with each student’s knowledge of iron deficiency issues (p < 0.05). The odds of refusal in the absence of a classroom water supply were 2.02 (95% CI 1 · 044 to 3 · 900) times greater than for those classrooms with a water supply. Student exposure to the program’s goal was satisfactory; however, delivery and fidelity of educational materials and training sessions were inadequate.

Conclusions

The findings suggest that the methods of delivery and the fidelity of the program components, education materials and training sessions were insufficient and need to be improved. Additionally, specific attention has to be given to contextual factors to ensure the success of the program.

Factors associated with non-use of antenatal iron and folic acid supplements among Pakistani women: a cross sectional household survey

Background

World Health Organization recommends a standard daily oral dose of iron and folic acid (IFA) supplements throughout pregnancy to begin as early as possible. The aim of the present study was to determine the prevalence of use of antenatal IFA supplements, and the socio-demographic factors associated with the non-use of antenatal IFA supplements from 14 selected districts in Pakistan.

Methods

Data was derived from a cross sectional household survey conducted in 14 project districts across Pakistan. Trained female field workers conducted interviews with married women of reproductive age from December 2011 to March 2012. Women with the most recent live births in the preceding five years of the survey were selected for this study. Data was analysed by using STATA 13 and adjusted for the cluster sampling design. Multivariate logistic regression models were constructed to identify the independent factors associated with the non-use of antenatal IFA supplements.

Results

Of 6,266 women interviewed, 2,400 (38.3%, 95% CI, 36.6%, 40.1%) reported taking IFA supplements during their last pregnancy. Among IFA users, the most common source of supplements was doctors (49.4%) followed by community health workers (40.3%). The mean (±SE) number of supplements used was 76.9 (±51.6), and the mean (±SE) month of pregnancy at initiation of supplementation was 5.3 (±1.7) months. Socio-demographic factors significantly associated with the non-use of antenatal IFA supplements were living in Dera Ghazi Khan district (AdjOR: 1.72), maternal age 45 years and above (AdjOR: 1.97), no maternal education (AdjOR: 2.36), no paternal education (AdjOR: 1.58), belonging to the lowest household wealth index quartile (AdjOR: 1.47), and no use of antenatal care (ANC) services (AdjOR: 13.39).

Conclusions

The coverage of antenatal IFA supplements is very low in the surveyed districts of Pakistan, and the lack of parental education, older aged women, belonging to poorest households, residence in Dera Ghazi Khan district and no use of ANC services were all significantly associated with non-use of these supplements. These findings highlight the urgent need to develop interventions targeting all pregnant women by improving ANC coverage to increase the use of antenatal IFA supplements in Pakistan.

Coverage, compliance and factors associated with utilization of iron supplementation during pregnancy in eight rural districts of Ethiopia: a cross-sectional study

Background

Despite the efforts to reduce iron deficiency during pregnancy, information on the coverage and factors associated with utilization of iron supplements is lacking. The study is intended to assess the coverage, compliance and factors associated with the use of prenatal iron supplements in eight rural districts of Ethiopia.

Methods

The study comprised two independent surveys conducted among pregnant women (n = 414) and women who gave birth in the preceding year of the survey (n = 1573). In both cases, respondents were selected using multistage sampling technique and data were collected via structured questionnaire. Predictors of iron supplement utilization (ranked categories of number of prenatal supplements taken) were identified using ordinal logistic regression. The outputs of the analysis are given using adjusted Odds Ratio (OR) with 95% Confidence Interval (CI).

Results

Among women who gave birth in the preceding year, 35.4% (95% CI: 31.3-39.5) were given/prescribed prenatal iron supplement during the index pregnancy and only 3.5% were supplemented for the recommended 91 or more days. Compared to women who had 4 or more ANC visits, those with 0, 1, 2 and 3 visits had 0.04, 0.33, 0.50 and 0.60 times less odds of iron supplement utilization, respectively. Women lacking comprehensive knowledge of anemia (OR = 0. 75 (95% CI: 0.57-0.97)) and those who weren’t informed about the importance of iron supplementation during the pregnancy (OR = 0. 05 (95% CI: 0.04-0.07)) had significantly lower utilization. On the other hand, in pregnant women the prevalence of anemia was 33.2%. Among pregnant women who were given/prescribed supplements, the average level of compliance was 74.9% and about 25.1% had less than 70% adherence. The leading reported reasons for non-adherence were side-effects (63.3%) and forgetfulness (16.7%).

Conclusion

Promoting early and frequent ANC, enhancing the quality of ANC counseling and promoting the knowledge of women on anemia are essential strategies for improving the utilization of iron supplements.

Evaluation of the Use of Intravenous Iron Supplements in an Obstetrics and Gynecology Department

Background: The use of intravenous (IV) iron sucrose was approved for the obstetric and gynecologic (OBGYN) population at our mother–child teaching hospital in 2006 for intolerance or nonresponse to oral iron supplements, contraindication to intramuscular (IM) iron, and rapid increase of the hemoglobin desired in iron-deficient patients. Objectives: ( a) To describe the indications and doses of IV iron sucrose used in OBGYN, ( b) to assess monitoring, and ( c) to describe the adverse effect profile. Methods: A retrospective study of patients admitted to the OBGYN wards with at least one prescription of IV iron from January 1, 2006, to March 31, 2010, was conducted. A standardized data collection sheet was used to record data. Results: A total of 164 prescriptions of IV iron were reviewed in 128 women. The indications for IV iron were anemia before delivery (n = 76), intolerance or no response to oral iron (n = 61), or intolerance or contraindication to IM iron (n = 27). Fourteen doses (9%) were appropriate, and the others were too low. Prior to prescription, ferritin or serum iron levels were assessed in 31% of women and hemoglobin electrophoresis in nearly all of Black or Asian women. One-week follow-up hemoglobin levels were measured after 66 prescriptions (40.2%). Adverse effects, mostly pain at the injection site, were reported in 18 (11%) occasions. Conclusions: IV iron is prescribed in OBGYN patients to obtain a rapid hemoglobin increase or when oral iron is not tolerated or inefficacious. The dose prescribed is generally too low, baseline essential testing often omitted, and appropriate follow-up monitoring incomplete. IV iron is well tolerated.

The effect of SMS messaging on the compliance with iron supplementation among pregnant women in Iran: a randomized controlled trial

We examined the effect of SMS text messages on compliance with iron supplementation among pregnant women. A randomized controlled trial was conducted on 116 pregnant women referred from public health centres in Ahvaz. Their gestational age was 14-16 weeks. The subjects were randomly assigned to a control group who received usual care, or to a 12-week intervention with SMS reminders in addition to usual care. Participants in both groups were provided with iron supplements and taught how to take iron tablets. Most women in the intervention group (94%) had high compliance with iron supplements compared to the control group (66%); this difference was significant (P = 0.003). Although haemoglobin, haematocrit and ferritin decreased significantly in each group, there was no significant difference between them. Using SMS reminders is an efficient way of improving compliance of women with iron supplementation during pregnancy. However, in the present study better compliance did not improve anaemia.

Psychological and social factors associated with late pregnancy iron deficiency anaemia in rural Viet Nam: a population-based prospective study

Objectives

The aim of this study was to examine the relationships between psychological and social factors and late pregnancy IDA among pregnant women in rural Viet Nam.

Methods

Pregnant women from 50 randomly-selected communes within Ha Nam province were recruited and assessed at 12 - 20 weeks gestation (Wave 1, W1). They were followed up in the last trimester (Wave 2, W2). IDA was defined as Haemoglobin < 11 g/dL and serum ferritin < 15 ng/mL. Symptoms of Common Mental Disorders (CMD) were assessed by the Edinburgh Postnatal Depression Scale-Vietnam (EPDS-V). Persistent antenatal CMD was defined as having an EPDS-V score ≥ 4 in both W1 and W2. Hypothesis models were tested by Structural Equation Modeling analyses.

Results

A total of 378 women provided complete data at both W1 and W2. The incidence risk of IDA in the third trimester was 13.2% (95% confidence interval (CI): 9.8-16.7). Persistent CMD was found in 16.9% (95% CI: 13.1-20.7) pregnant women and predicted by intimate partner violence, fear of other family members, experience of childhood abuse, coincidental life adversity, and having a preference for the sex of the baby. There was a significant pathway from persistent CMD to IDA in late pregnancy via the length of time that iron supplements had been taken. Receiving advice to take iron supplements and higher household wealth index were indirectly related to lower risk of late pregnancy IDA. Early pregnancy IDA and being multi-parous also contributed to late pregnancy IDA.

Conclusions

Antenatal IDA and CMD are prevalent public health problems among women in Viet Nam. The link between them suggests that while direct recommendations to use iron supplements are important, the social factors associated with common mental disorders should be addressed in antenatal care in order to improve the health of pregnant women and their infants.

A community-based cluster randomized controlled trial of "directly observed home-based daily iron therapy" in lowering prevalence of anemia in rural women and adolescent girls

In a community-based cluster randomized controlled trial, we randomly assigned clusters of anemic women and adolescent girls to either "directly observed home-based daily iron therapy" (DOHBIT; n = 524 in 16 villages) or unsupervised self-treatment at home (n = 535 in 16 villages) for a period of 90 days. Those in the DOHBIT group, when compared with those in the unsupervised self-treatment group, had significantly lower relative risk (RR) of anemia (16.8% vs 35.3%, RR = 0.47 [95% confidence interval (CI) = 0.33-0.65]; P < .0001), higher hemoglobin (Hb) rise of ≥2 g/dL (70.2% vs 42.2%, RR = 1.56 [95% CI = 1.31-1.87]; P <.0001), and nonsignificant trend for lower side effects (3.5% vs 6.7%, RR = 0.49 [95% CI = 0.22-1.08; P < .08) on intention-to-treat analyses. On linear mixed model analysis, the subjects in the intervention group demonstrated higher mean Hb levels (13.01 vs 12.32 g/dL; P < .0001) and higher adherence to iron therapy (93% vs 60%; P < .0001). DOHBIT is effective in lowering the prevalence of anemia in rural women and adolescent girls.

Maternal anemia in pregnancy: assessing the effect of routine preventive measures in a malaria-endemic area

We investigated the effectiveness of routine preventive measures for anemia in Beninese pregnant women during pregnancy. Anemia (hemoglobin < 110 g/L) was common: 68.3% at first antenatal visit (ANV1), 64.7% at second antenatal visit (ANV2), and 40.6% at delivery. Parasitic infections and nutritional deficiencies were the most preventable causes. After intermittent preventive treatment (IPTp) and antihelminthic treatments, malaria prevalence decreased from 15.1% (ANV1) to 4.0% (ANV2) and increased again to 9.6% at delivery. Helminth infections dropped from 11.1% (ANV1) to 7.2% (ANV2) and 2.4% at delivery. Malaria was associated with lower mean hemoglobin on ANV1 and delivery, and iron deficiency was associated with lower mean hemoglobin on ANV1 and ANV2. IPTp and antihelminthic treatments were efficacious to clear parasitic infections and improve hematologic status, whereas the effectiveness of daily iron and folic acid supplements to correct iron and folate deficiencies and decrease anemia was less marked, possibly because of lack of compliance.

ADHERENCE IN PREGNANCY: A SYSTEMATIC REVIEW OF THE LITERATURE

“Clinical decisions and research programs ultimately depend on the reliable and valid measurement of adherence. Yet, 50 years of research in this field have not provided the data necessary to answer critical measurement questions.”.

Anaemia in pregnancy

Anaemia in pregnancy, defined as a haemoglobin concentration (Hb) < 110 g/L, affects more than 56 million women globally, two thirds of them being from Asia. Multiple factors lead to anaemia in pregnancy, nutritional iron deficiency anaemia (IDA) being the commonest. Underlying inflammatory conditions, physiological haemodilution and several factors affecting Hb and iron status in pregnancy lead to difficulties in establishing a definitive diagnosis. IDA is associated with increased maternal and perinatal morbidity and mortality, and long-term adverse effects in the new born. Strategies to prevent anaemia in pregnancy and its adverse effects include treatment of underlying conditions, iron and folate supplementation given weekly for all menstruating women including adolescents and daily for women during pregnancy and the post partum period, and delayed clamping of the umbilical cord at delivery. Oral iron is preferable to intravenous therapy for treatment of IDA. B12 and folate deficiencies in pregnancy are rare and may be due to inadequate dietary intake with the latter being more common. These vitamins play an important role in embryo genesis and hence any relative deficiencies may result in congenital abnormalities. Finding the underlying cause are crucial to the management of these deficiencies. Haemolytic anaemias rare also rare in pregnancy, but may have life-threatening complications if the diagnosis is not made in good time and acted upon appropriately.

Role of iron supplementation in promoting maternal and fetal outcome

Background

The data comparing daily versus intermittent iron supplementation during pregnancy remain controversial. This study was undertaken to compare the efficacy of daily versus two different intermittent iron supplementation regimes on hematologic markers and birth outcomes in nonanemic pregnant women.

Methods

Two hundred and ten women with singleton pregnancies, no known disease, and hemoglobin levels >11.0 g/dL were randomly assigned to one of three groups, ie, Group A consuming two iron supplementation tablets once weekly (100 mg iron per week, n = 70), Group B consuming one tablet twice weekly (100 mg iron per week, n = 70) and Group C, consuming one tablet daily (50 mg iron per day, n = 70). No additional micronutrients were supplied. Hemoglobin and serum ferritin levels were measured at 20, 28, and 38 weeks. Pregnancy and birth outcomes (pregnancy termination, method of delivery, birth weight, stillbirth) were analyzed.

Results

In total, 201 women completed the protocol. There was a significant difference in mean hemoglobin and ferritin levels in Group B at 38 weeks (P = 0.018 and P = 0.035, respectively) but this difference was not clinically significant (hemoglobin >12 g/dL, ferritin >19 μg/L). There was a significant increase in ferritin in Group C (P = 0.03) at 28 weeks. No significant difference was observed with respect to pregnancy or birth outcome across the groups. All regimens prevented the occurrence of hemoglobin <10.5 g/dL, but weekly supplementation was associated with development of a hemoglobin level <11.0 g/dL (risk ratio 0.044).

Conclusion

Twice-weekly supplementation is as effective as daily supplementation, and may represent an acceptable compromise in iron supplementation regimens for nonanemic pregnant women.

A study to establish whether food-based approaches can improve serum iron levels in child-bearing aged women

BACKGROUND

Iron-deficiency anaemia is particularly prevalent in pregnancy. The present study aimed to determine whether functional bread containing teff flour (i.e. naturally rich in iron) could be an alternative way of improving iron status. However, before testing whether its consumption can improve pregnancy iron status, the bio-availability of iron was determined in a sample of nonpregnant women.

METHODS

Fifty-eight women (20-50 years) were recruited from the University. Blood samples were taken at baseline to assess iron status and participants were screened to account for other factors affecting iron status. Twenty-four participants (haemoglobin 9.5-14.0g dL(-1) ) were recruited to take part in the intervention and allocated to five groups: (i) control bread (CB); (ii) teff bread (TB); (iii) TB+level 1 phytase (TB+P1); (iv) TB+level 2 phytase (TB+P2); or (v) a supplement containing 10 mg of ferrous sulphate. Venous blood samples were taken before the intervention and after 180-210min, aiming to determine changes in serum iron.

RESULTS

Consuming three or four slices of TB provided statistically significantly more iron (7.6mg) than CB (5.1mg) (P<0.001). Because participants were fasted, serum iron levels declined in all bread groups (average -1.5μm), although the smallest reduction was observed in the TB+P2 group (-0.3 μm). The area-under-the-curve from baseline to 210min was lower in the TB+P2 (-78.8μmol min L(-1) ) group compared to the other bread interventions, indicating higher levels of iron absorption in this group.

CONCLUSIONS

The results obtained in the present study show that TB consumption may help to maintain serum iron levels, especially when phytase is added. The findings from the study also demonstrate there may be potential to further improve the bio-availability of iron from non-haem food sources.
