RESUMEN

BACKGROUND: The association of anemia with cognitive function and dementia remains unclear. OBJECTIVE: We aimed to investigate the association of anemia with cognitive function and dementia risk and to explore the role of inflammation in these associations. METHODS: Within the UK Biobank, 207,203 dementia-free participants aged 60+ were followed for up to 16 years. Hemoglobin (HGB) and C-creative protein (CRP) were measured from blood samples taken at baseline. Anemia was defined as HGB <13 g/dL for males and <12 g/dL for females. Inflammation was categorized as low or high according to the median CRP level (1.50 mg/L). A subset of 18,211 participants underwent cognitive assessments (including global and domain-specific cognitive). Data were analyzed using linear mixed-effects model, Cox regression, and Laplace regression. RESULTS: Anemia was associated with faster declines in global cognition (ß= -0.08, 95% confidence interval [CI]: -0.14, -0.01) and processing speed (ß= -0.10, 95% CI: -0.19, -0.01). During the follow-up of 9.76 years (interquartile range 7.55 to 11.39), 6,272 developed dementia. The hazard ratio of dementia was 1.57 (95% CI: 1.38, 1.78) for people with anemia, and anemia accelerated dementia onset by 1.53 (95% CI: 1.08, 1.97) years. The risk of dementia tended to be higher in people with both anemia and high CRP (1.89, 95% CI: 1.60, 2.22). There was a statistically significant interaction between anemia and CRP on dementia risk (p-interaction = 0.032). CONCLUSIONS: Anemia is associated with cognitive decline (specifically for processing speed) and increased risk of dementia, especially in people with high inflammation.

RESUMEN

Existing empirical evidence suggests that the prevalence of undernutrition in remote and poor, rural areas is still high among Chinese children. While evidence reveals that undernutrition may detrimentally affect child development, studies focusing on rural Chinese preschoolers are sparse. Using the baseline survey of a preschool's free nutritious lunch pilot program, this study examined the relationship between child undernutrition and developmental outcomes among a preschool-aged sample in poor, rural areas of China. We conducted the baseline survey in Hunan province in south central China in September 2018. A total of 1293 preschoolers living in two (then) nationally designated poverty counties in rural Hunan served as our study sample. Children's nutritional statuses were measured using height-for-age z-score, weight-for-age z-score, and anemia, while their cognitive and socio-emotional skills were assessed using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) and Strengths and Difficulties Questionnaire (SDQ), respectively. We find that 33% of sample preschoolers were anemic, whereas the incidences of stunting and wasting were 11% and 2%, respectively. About 54% of the sample children had delay in at least one of the developmental domains measured in this study. Our findings provide suggestive evidence supporting that children from certain backgrounds tend to experience worse nutritional and developmental outcomes than their counterparts. After controlling for socioeconomic status, we observed that both anemia and stunting were negatively associated with children's cognitive performance; however, they were not associated with socio-emotional performance. As such, this study suggests that free lunch programs have the potential to change children's developmental trajectory in preschool. We believe that our results will contribute to the debate surrounding whether the nutritious lunch program in China should be expanded to the preschool education level.

RESUMEN

BACKGROUND: In Pakistan, there is a dearth of literature on the perceptions of anemia among women of reproductive age (WRA). This study was undertaken to explore the perceptions of women, their husbands, and healthcare providers about anemia, its possible causes, and how anemia impacts maternal and child health in Thatta, Pakistan. METHODS: A qualitative study was conducted in Thatta, Pakistan from September to December 2018. Using a pre-tested semi-structured interview (SSI), we collected data to understand their definitions of anemia through ten focus group discussions (FGDs) with women and their partners and ten primary informant interviews (KIIs) with healthcare providers. We identified six major themes: (I) Knowledge and awareness of anemia, (II) Causes and consequences of Anemia, (III) Dietary practices, (IV) Knowledge and practices regarding the use of iron-folic acid supplements, (V) Factors influencing prevention and control of anemia and (VI) Women's health behavior. We analyzed the data through thematic analysis using NVivo 10 software. RESULTS: Most community members were not aware of the term anemia but described anemia as a condition characterized by 'blood deficiency' in the body. All study participants perceived anemia as an important health problem tending to cause adverse outcomes among WRA and their children. Study participants perceived gutka (chewable tobacco) consumption as an important cause of anemia. Healthcare providers identified short inter-pregnancy intervals, lack of family planning, poor health-seeking behavior, and consumption of unhealthy food as causes of anemia in the district. Consumption of unhealthy food might not be related to related to a poorer knowledge of iron-deficient foods, but economic constraints. This was further endorsed by the healthcare providers who mentioned that most women were too poor to afford iron-rich foods. All men and women were generally well versed with the sources of good nutrition to be consumed by WRA to prevent anemia. CONCLUSION: The findings suggest that the government should plan to develop strategies for poverty-stricken and vulnerable rural women and plan health awareness programs to improve dietary practices, compliance with supplements, and health-seeking behavior among women of reproductive age. There is a need to develop effective counseling strategies and context-specific health education sessions to improve the health-seeking behavior of women and men in the Thatta district of Pakistan. Besides, there is need to address social determinants of health such as poverty that pushes women of poorer socioeconomic strata to eat less nutritious foods and have more anaemia. Therefore, a comprehensive and robust strategic plan need to be adopted by government that focuses not only on the awareness programs, but also aim to reduce inequities that lead to pregnant women eat iron-poor foods, which, in turn, forces them to become anemic.

RESUMEN

OBJECTIVE: This study was conducted to determine the relationship between pica and anemia, gastrointestinal disorders, as well as pregnancy outcomes in pregnant women. METHODOLOGY: This study was a prospective study carried out between January 2016 and June 2017 and was performed on 226 pregnant women who attended four different health care centers to receive routine prenatal care. Sampling was done considering the inclusion criteria, in two steps: cluster sampling and random sampling. Data collection was done using a researcher-made checklist. The significance level was set at p = 0.05. RESULTS: The average age of the participants was 26.10±6.27. The prevalence of pica in pregnant women in the first, second, and third trimesters was 9.3, 8, and 2.1%, respectively. The most common pica craving among pregnant women was for ice and frozen materials (68.2%). There was a statistically significant relationship between gastrointestinal disorders and anemia with pica (p < 0.001). There was also a significant relationship between birth weights of babies born to mothers with pica and those without pica (p = 0.005). CONCLUSION: Pica in pregnant women had a significant relationship with gastrointestinal disorders and anemia during pregnancy and pregnancy outcomes. Thus, in addition to providing healthcare services, health care professionals should consider patients' pica practices and make the necessary interventions.

RESUMEN

BACKGROUND: Several observational studies have been conducted to investigate the link between anaemia and adult depression but have shown inconsistent results. This systematic review and meta-analysis was performed to investigate this association. METHODS: A comprehensive search of four electronic databases (PubMed, EMBASE, PsycINFO and the Cochrane Library) was conducted to identify relevant papers published up to November 2019 for the systematic review and meta-analysis. The Newcastle-Ottawa Scale was used to assess the methodological quality of selected studies. A random-effects model was used to draw metaestimates of the relationship between anaemia and adult depression. RESULTS: A total of 9706 papers were retrieved, and 14 observational epidemiological studies (9 case-control studies and 5 prospective cohort studies) comprising 10 764 cases of depression were finally included in this meta-analysis. The mean age of the participants ranged from 38.4 to 75.0 years. A significant association was identified between low haemoglobin levels and adult depression (OR or relative risk 1.43; 95% CI 1.23 to 1.65). Subgroup analyses according to study design, mean age, diagnostic criteria of anaemia, geographical region, number of participants, methodological quality and adjustment for various confounding factors such as education, smoking, comorbid disorders, physical activity, alcohol intake and medication use showed similar results. CONCLUSIONS: The current study showed that anaemia was related to an increased risk of adult depression. One of the important limitations of our study was a moderate degree of heterogeneity due to the variety of assessment tools used to identify depression and the existence of publication bias. Another limitation of this meta-analysis was the lack of prospective cohort studies.

RESUMEN

BACKGROUND: To evaluate impact of anemia on health-related quality of life (HRQOL) over time in a large pediatric cohort with mild-to-moderate chronic kidney disease (CKD). METHODS: Participants were enrolled in the Chronic Kidney Disease in Children Study (CKiD), a multicenter, longitudinal cohort. HRQOL was measured using the Pediatric Quality of Life Inventory (PedsQL). Anemia was defined as hemoglobin < 5th percentile for age, sex, and race. Two longitudinal analyses were conducted on consecutive visit pairs. Models examined effects of anemia status on both HRQOL score over time and change in HRQOL score between consecutive visits. The sample included 733 children with a median estimated GFR 54 ml/min/1.73 m2. Thirty percent of children had anemia at index visit. RESULTS: Analysis of HRQOL scores revealed the presence of anemia was associated with significantly lower overall HRQOL (ß = - 2.90 (95% CI = - 7.74, - 0.21), p = 0.04) and physical functioning (ß = - 5.72 (- 9.49, - 2.25), p = 0.001) according to children. On parent ratings, the development of anemia was associated with lower emotional functioning scores (ß = - 4.87 (- 8.72, - 0.11), p = 0.045). In the second model, children who developed anemia were rated by caregivers as having more decreased physical functioning than children who remained anemia-free (ß = - 3.30 per year (- 5.83, - 0.76), p = 0.01). Caregivers did not observe declines in their children's other PedsQL subscales in the presence of developed anemia. Children with resolved or persistence did not show improvement or decline in any aspect of HRQOL functioning relative to non-anemic subjects. CONCLUSIONS: In children with CKD, anemia has an adverse effect on HRQOL which persists over time but does not appear to be progressive.

RESUMEN

BACKGROUND: To reduce the prevalence of anemia, the Indian government recommends daily iron and folic acid supplements (iron supplements) for pregnant women and weekly iron supplements for adolescents and all women of reproductive age. The government has distributed free iron supplements to adolescents and pregnant women for over four decades. However, initial uptake and adherence remain inadequate and non-pregnant women of reproductive age are largely ignored. The aim of this study is to examine the multilevel barriers to iron supplement use and to subsequently identify promising areas to intervene. METHODS: We conducted a qualitative study in the state of Odisha, India. Data collection included key informant interviews, focus group discussions with women, husbands, and mothers-in-law, and direct observations in health centers, pharmacies and village health and nutrition days. RESULTS: We found that at the individual level, participants knew that iron supplements prevent anemia but underestimated anemia prevalence and risk in their community. Participants also believed that taking too many iron supplements during pregnancy would "make your baby big" causing a painful birth and a costly cesarean section. At the interpersonal level, mothers-in-law were not supportive of their daughters-in-law taking regular iron supplements during pregnancy but husbands were more supportive. At the community level, participants reported that only pregnant women and adolescents are taking iron supplements, ignoring non-pregnant women altogether. Unequal gender norms are also an upstream barrier for non-pregnant women to prioritize their health to obtain iron supplements. At the policy level, frontline health workers distribute iron supplements to pregnant women only and do not follow up on adherence. CONCLUSIONS: Interventions should address multiple barriers to iron supplement use along the socio-ecological model. They should also be tailored to a woman's reproductive life course stage: adolescents, pregnancy, and non-pregnant women of reproductive age because social norms and available services differ between the subpopulations.

RESUMEN

BACKGROUND: Reductions in health-related quality of life (HRQoL) in patients with chronic kidney disease (CKD) are thought to be exacerbated by the low hemoglobin (Hb) levels that define anemia, a common complication of CKD. The current analysis evaluated the impact of anemia on HRQoL and work productivity in patients with non-dialysis dependent and dialysis-dependent CKD using real-world data. METHODS: Data were collected in France, Germany, Italy, Spain, the UK, the USA and China in 2012-2018 in the Adelphi Real World Disease Specific Programme™ for CKD, a large, cross-sectional, survey of physicians and their patients. Patients completed three patient-reported outcomes (PRO) instruments: the EuroQol 5-Dimension 3-level (EQ-5D-3 L), the Kidney Disease Quality of Life (KDQOL-36) instrument and the Work Productivity and Activity Impairment questionnaire. PROs were assessed by CKD stage and Hb levels, and regression analyses were performed with CKD stage and Hb level as independent variables and PROs as outcome variables, while adjusting for age, sex, CKD stage, comorbidities and cardiovascular risk. RESULTS: Overall, 5276 patients participated in the survey, including 28% stage 4 and 36% dialysis patients. Patients with lower Hb levels more often reported problems/issues on all EQ-5D-3 L domains (p < 0.0001). Regression analyses showed significant associations between lower Hb levels and the probability of low (< 0.8) EQ-5D-3 L utility scores (p < 0.0001) and low visual analog scale scores (p < 0.05), indicating poorer health status. Associations were seen even when adjusting for CKD stage and other potential confounding factors. Significant associations were observed between Hb level and the 12-Item Short-Form Health Survey (SF-12) Physical Component Summary, SF-12 Mental Component Summary and the three KDQOL-36 subscales (all p < 0.0001), and were confirmed using linear regression analyses adjusting for CKD stage and other potential confounders. Numerically greater work productivity losses and greater activity impairment were observed with lower Hb levels. CONCLUSIONS: Lower Hb levels worsen the impact of CKD on HRQoL, and are associated with lower work productivity in patients with CKD. Assessment and treatment of anemia should be recognized as a key component of integral CKD management throughout all stages of the disease.

RESUMEN

OBJECTIVE: Over half of pregnant women in India are affected by anaemia, which can lead to premature birth, low birth weight and maternal and child mortality. Using formative research, we aimed to understand social and cultural factors around iron and folic acid (IFA) supplement provision and adherence to identify potential strategies for improving adherence and behaviours to prevent and treat anaemia among pregnant and lactating Indian women. DESIGN: In-depth interviews and focus group discussions with women and key informant interviews with health officials and workers. SETTING: Four districts in two Indian states: Allahabad and Bara Banki districts in Uttar Pradesh and Chikkballapura and Mandya districts in Karnataka. PARTICIPANTS: Pregnant and lactating women (n 65) and district officials and community health workers (n 14). RESULTS: Most women were aware of anaemia but did not understand its seriousness and consequences. All women received IFA supplements (predominantly for free), but many were not adherent because of side effects; lack of information from healthcare providers on the causes of anaemia, its seriousness and solutions and low social support. To address anaemia, women were most confident in their ability to prepare and eat healthier foods but lacked control over resources such as appropriate food availability. CONCLUSIONS: Based on the findings, we recommend multicomponent interventions to train healthcare providers, address systemic barriers and involve family members to support IFA supplement adherence and dietary changes. Future research will determine which strategies are most effective to reduce the burden of anaemia in India among pregnant and lactating women.

RESUMEN

BACKGROUND: Cognitive and motor-performance decline with age and the process is accelerated by decline in general health. In this study, we aimed to estimate the effects of COPD and HB levels on cognitive and motor performance in the general older population and assess potential interaction. METHODS: The English Longitudinal Study of Aging is a population-based cohort study including measurements of lung-function and HB levels together with cognitive and motor performance testing. Data were collected from 5709 participants including three measurement time over eight years. COPD was defined using lung-function-parameters and clinical symptoms. HB was assessed continuously and low HB was defined using clinical anemia cutoffs. Linear mixed-effects regression models were used to quantify the associations of COPD and HB with outcome measures, both individually and in combination. RESULTS: Participants with both low HB and COPD demonstrated worse motor performance compared to individuals with only one exposure, resulting in up to 1 s (95%CI, 0.04-1.8) longer time needed to complete the five times sit to stand task than what would be expected based on purely additive effects. Additionally in individuals with COPD, the time to complete the motor-performance task per unit decrease in continuous HB levels was longer than in participants without COPD after full adjustment for confounding (up to 1.38 s/unit HB level, 95% CI: 0.65-2.11). CONCLUSION: In persons with COPD low HB levels may contribute to low motor-performance in a supra additive fashion. Further studies should re-evaluate whether earlier treatment of lower HB in these individuals might be beneficial.

RESUMEN

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.

RESUMEN

Monocytes are plastic heterogeneous immune cells involved in host-parasite interactions critical for malaria pathogenesis. Human monocytes have been subdivided into three populations based on surface expression of CD14 and CD16. We hypothesised that proportions and phenotypes of circulating monocyte subsets can be markers of severity or fatality in children with malaria. To address this question, we compared monocytes sampled in children with uncomplicated malaria, severe malarial anaemia, or cerebral malaria. Flow cytometry was used to distinguish and phenotype monocyte subsets through CD14, CD16, CD36 and TLR2 expression. Data were first analysed by univariate analysis to evaluate their link to severity and death. Second, multinomial logistic regression was used to measure the specific effect of monocyte proportions and phenotypes on severity and death, after adjustments for other variables unrelated to monocytes. Multivariate analysis demonstrated that decreased percentages of non-classical monocytes were associated with death, suggesting that this monocyte subset has a role in resolving malaria. Using univariate analysis, we also showed that the role of non-classical monocytes involves a mostly anti-inflammatory profile and the expression of CD16. Further studies are needed to decipher the functions of this sub-population during severe malaria episodes, and understand the underlying mechanisms.

RESUMEN

BACKGROUND: Our objective was to characterize the relationship of anemia and hemoglobin concentrations with cross-sectional cognitive functions and changes in cognitive functions over 2 years in a large sample of Chinese middle aged and elderly. METHODS: Ten thousand nine hundred eighteen adults aged 45 years or older participating in the China Health and Retirement Longitudinal Study (CHARLS) were used for cross-sectional analyses and 9324 were used for longitudinal analysis. Cognitive functions were assessed by memory recall (episodic memory), mental status (TICS), and global cognitive function at baseline survey (Visit 1) and first follow-up survey (Visit 2). The lower the cognitive test score, the worse the cognitive function. Anemia was defined as hemoglobin concentrations lower than 13 g/dl for men and lower than 12 g/dl for women. Adjusted multivariate regression analyses were used to explore the relationships of different cognitive domains with anemia and hemoglobin concentration. RESULTS: Overall, the prevalence of anemia was 12.86% and the mean hemoglobin concentration was 14.37 ± 2.20 g/dl. After adjusting for socio-demographic and health-related covariates, the cross-sectional association between anemia and global cognitive function [ß (95%CI) = - 0.49(- 0.69~ - 0.29)], episodic memory [ß (95%CI) = - 0.14(- 0.23~ - 0.05)], and TICS [ß (95%CI) = - 0.23(- 0.38~ - 0.08)] were significant and did not differ by gender. The hemoglobin concentration was also associated with global cognitive function among the whole sample (P < 0.05 for all). The longitudinal analyses showed global cognitive function and episodic memory were associated with anemia independent of covariates (P < 0.05 for all). Sensitivity analyses further provided significant results showing the association between anemia and cognition decline (P < 0.05). CONCLUSION: There was a cross-sectional and longitudinal association between anemia and accelerated decline in cognitive functions in Chinese middle-aged and elderly. This suggests that anemia and low hemoglobin concentrations are independent risk factors of cognitive decline.

RESUMEN

BACKGROUND: Prevalence of both anemia and cognitive impairment tends to increase with age. Individual studies have recently shown that anemia could be associated with cognitive impairment. OBJECTIVE: To investigate the association between anemia and cognitive impairment including dementia. METHODS: Two of the authors systematically searched PubMed, EMBASE, and the Cochrane library to retrieve observational studies reporting a relationship between anemia and cognitive impairment from 1964 to July 10, 2019. Case-control and cohort studies were included, and odds ratios (ORs) or relative risks (RRs) with 95% confidence intervals (CIs) for the risk of cognitive impairment were calculated using a random-effects model. RESULTS: In total, 16 observational studies including eight case-control studies and eight cohort studies were included in the final analysis. Anemia was significantly linked to cognitive impairment (OR or RR 1.51; 95% CI: 1.32-1.73) in a random-effects meta-analysis, albeit with medium heterogeneity (I2 = 47.8%). Meta-estimates of dementia from prospective population-based cohort studies were similar (RR 1.46; 95% CI: 1.22-1.76) without substantial heterogeneity (I2 = 23.2%). CONCLUSION: Our meta-analysis indicates that anemia is associated with cognitive impairment. Further prospective research is warranted to determine the cause-effect relationship of anemia with cognitive impairment and whether treatment of anemia might reduce the risk of dementia.

RESUMEN

BACKGROUND: Nutritious underutilized foods (NUFs) significantly contribute to sustainable dietary diversity but are often unused for many reasons. OBJECTIVE: We assessed the influence of food security status (FSS) and anemia-related knowledge (ARK) on perceptions about Solanum torvum (turkey berry) and Rhynchophorus phoenicis Fabricius (palm weevil larvae) among Ghanaian caregivers. METHODS: A cross-sectional survey was conducted among 891 caregivers (aged 20-49 years), who have children 6 to 59 months old, from Upper Manya Krobo district (Eastern region), Kumasi metropolitan (Ashanti region), Ho municipality (Volta region), La-Nkwantanang-Madina, and Ga West municipality (Greater-Accra region), Ghana. Food security status, ARK, and perceptions about the 2 NUFs were obtained using pretested semi-structured questionnaire. Logistic regression models were used to determine effect of FSS and ARK on perception outcomes. RESULTS: Thirty-six percent of caregivers were food secure, while 13.9%, 28.4%, and 21.7%, respectively, were mildly, moderately, and severely food insecure. Most caregivers (62.0%) scored above 70% on ARK. High favorable perception was significantly lower for palm weevil larvae than that for turkey berry. Food secure caregivers were 4.5 times more likely to have poor favorable perceptions about palm weevil larvae than food insecure caregivers (P = .03). However, food secure caregivers were 2.9 times more likely to have high favorable perceptions about turkey berry than food insecure caregivers (P < .001). Caregivers' knowledge about anemia was associated with high favorable perception about turkey berry by 3.3-fold (95% confidence interval: 2-5.5, P = .001). CONCLUSIONS: Nutrition education about turkey berry and palm weevil larvae is needed to encourage their use for promoting nutrient density of complementary and household foods.

RESUMEN

OBJECTIVES: A diagnosis of hypertensive disorders during pregnancy (HDPs) or gestational diabetes mellitus (GDM) is highly predictive of women at increased risk of developing chronic hypertension, Type 2 diabetes, and cardiovascular disease. This study investigates perceptions of women and healthcare providers in rural India regarding these long-term risks. DESIGN: Qualitative study using modified grounded theory. SETTING: Two states in rural India: Haryana and Andhra Pradesh. POPULATION: Pregnant and postpartum women, community health workers (CHWs), primary care physicians, obstetricians, laboratory technicians, and healthcare officials. METHODS: In-depth interviews and focus group discussions explored: (1) priorities for high-risk pregnant women; (2) detection and management of HDPs and GDM; (3) postpartum management, and (4) knowledge of long-term sequelae of high-risk conditions. A thematic analysis was undertaken. RESULTS: Seven focus group discussions and 11 in-depth interviews (n = 71 participants) were performed. The key priority area for high-risk pregnant women was anaemia. Blood pressure measurement was routinely embedded in antenatal care; however, postpartum follow up and knowledge of the long-term complications were limited. GDM was not considered a common problem, although significant variations and challenges to GDM screening were identified. Knowledge of the long-term sequelae of GDM with regard to an increased risk of Type 2 diabetes and cardiovascular disease among doctors was minimal. CONCLUSIONS: There is a need for improved education, standardisation of testing and postpartum follow up of HDPs and GDM in rural Indian settings. FUNDING: SN is supported by an MRC Clinical Research Training Fellowship (MR/R017182/1). The George Institute for Global Health Global Women's Health programme provided financial support for the research assistant and fieldwork costs in India. TWEETABLE ABSTRACT: Improved education and postpartum care of women with hypertension and diabetes in pregnancy in rural India are needed to prevent long-term risks.

RESUMEN

Anemia is a condition in which the number of red blood cells is not sufficient to meet the physiological need of the body. Women of reproductive age and pregnant women are at a high risk of anemia, which in turn may contribute to maternal morbidity and mortality. We aimed to describe the prevalence of anemia and the factors associated with the risk of developing anemia in women of reproductive age in Nepal. Additionally, we examined the association of women's decision-making autonomy regarding healthcare and experience of intimate partner violence (IPV) with anemia. Data from the 2016 Nepal Demographic and Health Survey (NDHS) were used in this study. The data were adjusted for sampling weight, stratification, and cluster sampling design. A battery-operated portable HemoCue was used to measure hemoglobin and detect anemia. Using complex sample logistic regression, the association between dependent and independent variables were examined; crude and adjusted odds ratio were reported. The mean (± SD) hemoglobin concentration was 12.13 g/dL (± 1.48). Overall, about 41% (95% CI 38.6-43.0%) of women aged 15-49 years were anemic. Women in households with wells as the source of drinking water (aOR 1.93; 95% CI 1.58-2.37) were significantly associated with an increased risk of developing anemia. While women who were currently using hormonal contraceptives (aOR 0.63, 95% CI 0.52-0.76) were significantly less likely to be anemic. After adjusting for background characteristics among women who were married at the time of the survey, decision-making autonomy regarding healthcare, and experience of IPV did not have a significant association with anemia. The high prevalence of anemia suggests the need for substantial improvement in the nutritional status of women. The increased disease burden compared with the past survey highlights the needs to reconsider the existing nutritional policy in Nepal.

RESUMEN

In a highly patriarchal society such as India, and many Middle Eastern, African, and East Asian countries, coresidence with the mother-in-law is ubiquitous during the early years of marriage. During the period when women have to make crucial fertility decisions, they are under the supervision of the mother-in-law. Using the National Family Health Survey 2005-2006, and estimation strategies such as propensity score (PS) weighted regressions and a difference-in-differences type approach with PS matching, we estimate the causal effect of coresidence during pregnancy on maternal anemia among rural women in India. Here, coresidence and non-coresidence during pregnancy define our treatment and control, respectively. Women coresiding with both in-laws had fewer children, were younger, more educated, wealthier, and less likely to be Muslim and from scheduled castes and tribes compared to non-coresident women. Results indicate that the mother-in-law is a potentially valuable resource during pregnancy. For example, living with the mother-in-law reduced the likelihood of moderate to severe anemia by 13.2 percentage points compared to no coresidence. Under joint coresidence with both in-laws, the effect dropped to 8.5 percentage points. Moreover, women living with the mother in-law were 16.8 percentage points more likely to receive any iron supplementation. From a public health perspective and for policy making, the results indicate that safe motherhood programs should be augmented with awareness generation components which target the mother-in-law. Furthermore, pregnant women in nuclear families need particular attention.

RESUMEN

Aims: The overall cost and health-related quality of life (HRQoL) associated with current treatments for chronic kidney disease (CKD)-related anemia are not well characterized. A systematic literature review (SLR) was conducted on the costs and HRQoL associated with current treatments for CKD-related anemia among dialysis-dependent (DD) patients. Materials and methods: The authors searched the Cochrane Library, MEDLINE, EMBASE, NHS EED, and NHS HTA for English-language publications. Original studies published between January 1, 2000 and March 17, 2017 meeting the following criteria were included: adult population; study focus was CKD-related anemia; included results on patients receiving iron supplementation, red blood cell transfusion, or erythropoiesis stimulating agents (ESAs); reported results on HRQoL and/or costs. Studies which included patients with DD-CKD, did not directly compare different treatments, and had designs relevant to the objective were retained. HRQoL and cost outcomes, including healthcare resource utilization (HRU), were extracted and summarized in a narrative synthesis. Results: A total of 1,625 publications were retrieved, 15 of which met all inclusion criteria. All identified studies included ESAs as a treatment of interest. Two randomized controlled trials reported that ESA treatment improves HRQoL relative to placebo. Across eight studies comparing HRQoL of patients achieving high vs low hemoglobin (Hb) targets, aiming for higher Hb targets with ESAs generally led to modest HRQoL improvements. Two studies reported that ESA-treated patients had lower costs and HRU compared to untreated patients. One study found that aiming for higher vs lower Hb targets led to reduced HRU, while two other reported that this led to a reduction in cost-effectiveness. Limitations: Heterogeneity of study designs and outcomes; a meta-analysis could not be performed. Conclusions: ESA-treated patients undergoing dialysis incurred lower costs, lower HRU, and had better HRQoL relative to ESA-untreated patients. However, treatment to higher Hb targets led to modest HRQoL improvements compared to lower Hb targets.
