RESUMO

We aimed to determine the variations in the prevalence of childhood anemia according to the ethnic group before and during the COVID-19 pandemic in Peru. Secondary analysis of the Demographic and Family Health Survey during 2016-2021. The outcome variable was anemia, and the exposure variable was maternal ethnicity. Also, we included sociodemographic and clinical confounding variables. We constructed generalized linear models of the Poisson family with a logarithmic link function. We evaluated 85,905 records; 30.34% had anemia, 50.83% were mestizo, 25.98% were Quechua, and 2% were Aymara. Compared with mestizos, Quechua children (PR: 1.11; 95% CI: 1.07-1.15; p < 0.001), Aymara (PR: 1.35; 95% CI: 1.27-1 .44; p < 0.001), natives of the Amazon (PR: 1.20; 95% CI: 1.12-1.28; p < 0.001) and those who belonged to other indigenous peoples (PR: 1.29; 95% CI: 1.05-1.57; p = 0.013) had a higher prevalence of childhood anemia. On the contrary, compared to mestizos, white children had a lower prevalence of anemia (PR: 0.93; 95% CI: 0.89-0.99; p = 0.019). During the COVID-19 pandemic, compared to mestizos, only Quechua (PR: 1.15; 95% CI: 1.08-1.23; p < 0.001) and Aymara (PR: 1.38; 95% CI: 1.23-1.55; p < 0.001) had a higher prevalence of childhood anemia. Except for Afro-descendants, children from 6 to 59 months of age who belong to an ethnic minority had a higher probability of having childhood anemia than mestizos. However, only Quechua and Aymara children had higher odds of anemia during the COVID-19 pandemic than mestizos.

RESUMO

Anemia in pregnancy (AIP) is associated with poor maternal/fetal outcomes. The prevalence of AIP globally ranges from 44-53% and varies drastically depending on maternal race/ethnicity and other factors. Screening and treatment of AIP is disputed. This study is a retrospective review of electronic medical records (EMR) of pregnant adults over three years (2018-2020, inclusive) of Sanford Health, a large healthcare system in the upper Midwest. AIP was determined by either diagnosis or lab values (hemoglobin, hematocrit, and ferritin) overlapping with pregnancy. A missed diagnosis was characterized by confirmed anemia through lab values but lacking a diagnosis of anemia within EMR. A total of 35,498 patients were included in this study, 42.9% were determined to have AIP. Of AI/AN (American Indian/Alaska Native) patients, 58.3% were anemic and 55.1% of Black/African American patients were anemic compared to 40.0% of anemic white patients. Of anemic patients, 81.1% did not have an anemia diagnosis listed in EMR. This study identifies racial and ethnic disparities of AIP among patients in the upper Midwest. In addition, this study highlights the need for improved data integrity within EMR.

RESUMO

The double burden of malnutrition (DBM) affects many low- and middle-income countries. However, few studies have examined DBM at the individual level, or undernutrition and overnutrition co-occurring within the same person. This study aims to investigate the prevalence and determinants of DBM among adults in the Philippines. Data from the 2013 National Nutrition Survey were used. The sample size in the analysis was 17,010 adults aged ≥20 years old, after excluding pregnant and lactating women. DBM was defined as the co-occurrence of overweight/obesity and anemia (definition #1), overweight/obesity and anemia or vitamin A deficiency (definition #2), and overweight/obesity and anemia or vitamin A deficiency or iodine insufficiency (definition #3). Anthropometric measurements and biochemical markers were used for DBM assessment. Data were analyzed using descriptive statistics, the chi-square test, and logistic regression by R software. Results showed that definition #3 is the predominant type of DBM (7.0%) in the general population, whereas the prevalence of DBM has increased to 23.7% in overweight/obese persons. Sex, age, educational attainment, marital status, household size, wealth quintile, and smoking status were the determinants of DBM. This study revealed that Filipino adults experience malnutrition critically and must be addressed through food and nutrition interventions.

RESUMO

We analyzed the effect of anemia on tumor response of patients with primary invasive breast cancer (BC) receiving neoadjuvant chemotherapy (NACT). The patient collective was very homogenous; finally, 74 BC patients with identical medication and duration of NACT were enrolled. After completion of NACT, 49 patients (66.2%) had a post-NACT Hb level <12 g/dl. In the anemic group, we found a tendency of lower median tumor response compared to nonanemic patients at this time (15 versus 17 mm, retrospectively, p = 0.18). Age at diagnosis significantly correlated with the difference of Hb [before initiation - after completion of NACT] (correlation coefficient = 0.40, p < 0.001).

RESUMO

OBJECTIVE: South Africa has a high burden of HIV infection and anaemia. These conditions may cause HbA1c to over- or underestimate glycaemia; however, this has not been comprehensively investigated in African populations. We assessed the association of anaemia, HIV infection and antiretroviral therapy (ART) with HbA1c , and implications for the detection and diagnosis of diabetes, in a black South African population. RESEARCH DESIGN AND METHODS: In this population-based cross-sectional study in eThekwini municipality (Durban), South Africa, we assessed HbA1c and conducted oral glucose tolerance tests (OGTTs), HIV diagnostic tests and full blood count measurements among 1067 participants without a history of diabetes diagnosis. Linear regression was used to examine differences in HbA1c by anaemia (comparator: no anaemia), or HIV and ART (comparator: no HIV) status. HbA1c -based diabetes prevalence was compared with OGTT-based prevalence among individuals with anaemia and with untreated and ART-treated HIV. RESULTS: In adjusted analyses, normocytic and microcytic anaemia were associated with higher HbA1c compared with no anaemia, whereas macrocytic anaemia and ART-treated HIV were associated with lower HbA1c compared with no anaemia and no HIV, respectively. However, magnitudes of association were small (range: ß  = -3.4 mmol/mol or -0.31%, p < 0.001 [macrocytic anaemia] to ß = 2.1 mmol/mol or 0.19%, p < 0.001 [microcytic anaemia]). There was no significant difference in diabetes prevalence based on HbA1c or OGTT among individuals with anaemia (2.9% vs. 3.3%, p = 0.69), untreated HIV (1.6% vs. 1.6% p = 1.00) or ART-treated HIV (2.9% vs. 1.2%, p = 0.08). CONCLUSIONS: Our results suggest that anaemia and HIV status appear unlikely to materially affect the utility of HbA1c for diabetes detection and diagnosis in this population. Further studies are needed to examine these associations in sub-Saharan African populations.

RESUMO

In Botswana, there is limited data available on the health and nutritional status of the San People (also known as the Basarwa or Bushmen), an Indigenous minority group primarily living in the Ghanzi District. Our aim in this study was to assess anemia prevalence among and anthropometric indices of women and young children in Ghanzi District through a cross-sectional survey. We recruited 367 mother-child pairs (women 15-49 years and children 6-59 months) in nine randomly selected areas. A capillary blood sample was collected, and weight and height were measured. Hemoglobin (Hb) concentration was measured with use of a hemoglobinometer (HemoCue, AB), as per global recommendations. Overall, adjusted anemia prevalence was 12% in non-pregnant women (Hb < 120 g/L), 26% in pregnant women (Hb < 110 g/L), and 42% in children (Hb < 110 g/L), but it varied widely depending on whether or not the controversial factor of ethnicity was adjusted for (range of 6-26%, 22-30%, and 35-68% prevalence, respectively). Thirty-nine percent (n = 133/344) of non-pregnant women and 52% (n = 12/23) of pregnant women were underweight (BMI < 18.5 kg/m2). In children aged 6-23 months, 41% were underweight (weight-for-age z-score < -2 SD), 13% were wasted (weight-for-height z-score < -2 SD), and 65% were stunted (height-for-age z-score < -2 SD); in children aged 24-59 months, 57% were underweight, 13% were wasted, and 66% were stunted. Fifty-six percent (n = 205/367) of women self-reported smoking in any form (rolled cigarettes or snuffing). The high prevalence of smoking among women, underweight status among pregnant women, and anemia, stunting, and wasting among children is of the highest concern for public health and should be addressed in future health and nutrition programming.

RESUMO

BACKGROUND: Anemia is common during pregnancy and the puerperium. The association of ethnicity as well as other characteristics with anemia and compliance with healthcare recommendations has not been studied sufficiently and needs to be explored in order to implement a targeted health policy. We examined the association between ethnicity and the risk for prenatal and puerperium anemia and the compliance with healthcare recommendations. This effort aims to guide reforms in policies and practices that will assist in decreasing anemia prevalence in Israel. METHODS: This study was a secondary analysis of a prospective cohort study database including 1558 women who delivered vaginally at Emek Medical Center. Anemia was assessed before delivery by obtaining a complete blood count (CBC). After delivery, CBCs were taken in cases of postpartum hemorrhage, symptoms consistent with anemia, prenatal anemia or other clinical indications. The study population was divided according to their ethnicity (Jews and Arabs). The primary outcomes were anemia before delivery, anemia in the immediate postpartum and 6 weeks postpartum, and compliance with healthcare recommendations, which was defined as the rate of women who performed a routine CBC test 6-weeks-postpartum. RESULTS: The rates of anemia before delivery and in the puerperium period were similar between Jews and Arabs (before delivery: 88 (11%) versus 98 (14%); 6 weeks postpartum: 55 (21%) vs 68 (28%), respectively;p > 0.05). Iron supplementation was high in both groups during pregnancy (~ 90%) and lower during the postpartum for Jews compared to Arabs (72% vs 83%,respectively; P < .0001). Only one third of the patients performed a CBC 6-weeks-postpartum regardless of ethnicity. CONCLUSION: Overall compliance with health recommendation was high during pregnancy but low postpartum and was reflected in anemia persistence regardless of ethnicity. Because of the adverse long term impact of anemia on patient's health, new policies need to be developed to improve patient's compliance postpartum. A possible strategy is to combine the follow-up of the mother with the one of the newborn in the family health stations (Tipat Halav) and the community clinics similarly to the close follow-up during pregnancy. Additional methods may include active summoning for CBC test and assuring iron supplement consumption.

RESUMO

BACKGROUND: A series of policy changes in 2011 altered reimbursement arrangements and guidance on use of erythropoiesis-stimulating agents for end-stage renal disease (ESRD) patients with anaemia in the US. While the policy changes were principally directed at care delivered in an outpatient setting, these had the potential to affect inpatient care also. This study used HCUP-NIS data (2008-2016) to examine trends in recorded anaemia among ESRD hospitalizations and analyse disparities in inpatient outcomes among ethnic groups following policy changes. METHODS: The International Classification of Diseases codes were used to identify ESRD admissions, recorded anaemia due to chronic kidney disease (CKD), and to generate an age-adjusted Deyo-Charlson comorbidity index. Linear splines with a knot placed at the time point of policy changes and multivariable logistic regression were used to examine the likelihood of recorded anaemia, adjusted for a range of socio-demographic and clinical covariates. Difference-in-difference analyses investigated the impact of policies on recorded anaemia. Other outcomes included hospital cost, mortality and place of discharge. RESULTS: The percentage of inpatient episodes with recorded anaemia arising from CKD increased from 26.2% in 2008 to 50.0% in 2016. Anaemia was more likely to be recorded as a complication of ESRD among minority ethnic groups and Native American admissions, in particular, (OR 1.20, 95%CI 1.15-1.25) relative to White American admissions; and these disparities widened following changes to reimbursement. Minorities were less likely to die in hospital and to be discharged to another healthcare facility, and (with the exception of Black American admissions) they were more expensive to treat. CONCLUSIONS: Our findings provide evidence of an increase in recorded anaemia consistent with a shift of patients from outpatient to inpatient settings in the wake of changes to reimbursement enacted in 2011. In addition, the study highlights the existence of ethnic disparities that widened after the policy initiated reimbursement changes.

RESUMO

BACKGROUND: Because of increasing safety concerns related to erythropoiesisstimulating agents (ESAs), the Centers for Medicare & Medicaid Services issued a Medicare reimbursement policy change regarding these medications in cancer patients. However, the policy established an absolute hemoglobin or hematocrit threshold to qualify for reasonable use but did not take the effect of gender and racial/ethnic differences in hemoglobin levels into consideration. OBJECTIVE: To examine disparities in the use of ESAs and blood transfusions after the Medicare policy change. METHODS: This study was an exploratory treatment effectiveness study and used the SEER-Medicare linked database. The treatment group was composed of cancer patients, whereas the control group was composed of chronic kidney disease patients. An interrupted time series design was used to examine the effect of the Medicare policy change on the use of ESAs and blood transfusions in different gender and racial/ethnic groups. RESULTS: The Medicare reimbursement policy change had an immediate effect on reducing the use of ESAs by 50% and increasing the use of blood transfusions by 10%. The immediate effect of the policy change on the monthly utilization of ESAs was 2 times greater in females (60% reduction) than males (30% reduction). Females had a 10% immediate increase in the monthly utilization of blood transfusions after the policy change. The policy change had the same immediate effect of a 50% reduction on the use of ESAs for Whites, African Americans/Blacks, and Latinos. African Americans/Blacks had a 50% immediate increase in the monthly utilization of blood transfusions after the policy change. CONCLUSIONS: Gender and racial/ethnic disparities were associated with the Medicare reimbursement policy change in the use of ESAs and blood transfusions. Thus, future policy considerations should keep biologic differences across gender and racial/ethnic groups in mind. DISCLOSURES: This study was funded by the SPARC Research Grant. The funder had no role in any part of this study. The authors have nothing to disclose.

RESUMO

OBJECTIVES: To identify maternal and perinatal risk factors associated with childhood anaemia. METHODS: A retrospective cohort study was conducted in three remote Katherine East Aboriginal communities in Northern Territory, Australia. Children born 2004-2014 in Community A and 2010-2014 in Community B and C, and their respective mothers were recruited into the study. Maternal and child data were linked to provide a longitudinal view of each child for the first 1000 days from conception to 2-years of age. Descriptive analyses were used to calculate mean maternal age, and proportions were used to describe other antenatal and perinatal characteristics of the mother/child dyads. The main outcome was the prevalence of maternal anaemia in pregnancy and risk factors associated with childhood anaemia at age 6 months. RESULTS: Prevalence of maternal anaemia in pregnancy was higher in the third trimester (62%) compared to the first (46%) and second trimesters (48%). There was a strong positive linear association (R2 = 0.46, p < 0.001) between maternal haemoglobin (Hb) in third trimester pregnancy and child Hb at age 6 months. Maternal anaemia in pregnancy (OR 4.42 95% CI 2.08-9.36) and low birth weight (LBW, OR 2.62, 95% CI 1.21-5.70) were associated with an increased risk of childhood anaemia at 6 months of age. CONCLUSIONS FOR PRACTICE: This is the first study to identify the association of maternal anaemia with childhood anaemia in the Australian Aboriginal population. A review of current policies and practices for anaemia screening, prevention and treatment during pregnancy and early childhood would be beneficial to both mother and child. Our findings indicate that administering prophylactic iron supplementation only to children who are born LBW or premature would be of greater benefit if expanded to include children born to anaemic mothers.

RESUMO

OBJECTIVE: To determine the presence of racial/ethnic differences in patients with anemia and serum folate deficiency. METHODS: We performed a retrospective analysis of data from patient samples collected from January 2010 to October 2018. Reference laboratory ranges were determined by Mayo Clinic Reference Laboratories. Race and ethnicity were classified according to National Institutes of Health categories. RESULTS: The analysis comprised 197 974 samples. Hemoglobin, hematocrit, and SF results were available for 173 337, 173 056, and 129 760 samples, respectively. Of the samples, 46 505 (26.8%) showed anemia, with a higher prevalence among American Indian/Alaskan Natives (AI/AN) 42.9% and African Americans (AA) 47.2% (P < .001). SF deficiency was present in 897 (0.7%), with a higher prevalence among AI/AN (9, [1.4%]) and AA (78, [1.2%]) and a lower prevalence in non-Hispanic whites (NHW) (758, [0.7%]), Hispanics (40, [0.6%]), and Asians (8, [0.3%]). In multivariable analysis, the prevalence of anemia was higher in all non-NHW racial/ethnic groups: AA (OR, 3.67, [95%CI: 3.47-3.88, P < .001]), AI/AN (OR, 3.25, [95%CI: 2.71-3.90, P < .001]), Asians (OR, 1.62, [95%CI: 1.47-1.77, P < .001]), and Hispanics (OR, 1.41, [95%CI: 1.32-1.50, P < .001]). SF deficiency was more common in AA (OR, 1.48, [95%CI: 1.17-1.88, P.001]) and less common in Asians (OR, 0.35, [95%CI: 0.17-0.70, P = .003]), compared with NHW. CONCLUSIONS: We showed significant racial/ethnic differences in anemia and SF deficiency. Differences were observed especially among NHW, AA, and Asians. We believe that these differences may be explained by social determinants of health. More research is needed regarding the causes of these differences and their clinical implications at a population level.

RESUMO

BACKGROUND: Anemia is a major concern for children in Nepal; however, little is known about context-specific causes of anemia. OBJECTIVE: We used cross-sectional data from the 2016 Nepal National Micronutrient Status Survey to evaluate factors associated with anemia in a nationally representative, population-based sample of children 6-59 mo (n = 1367). METHODS: Hemoglobin, biomarkers of iron status and other micronutrients, infection, inflammation, and blood disorders were assessed from venous blood samples. Soil-transmitted helminth (STH) and Helicobacter pylori infections were assessed from stool. Anthropometry was measured with standard procedures. Sociodemographic and household characteristics, diet, micronutrient powder (MNP) intake, pica, and morbidity recall were ascertained by caregiver interview. Multivariable logistic regression that accounted for complex sampling design, determined predictors of anemia (hemoglobin <11.0 g/dL, altitude adjusted); candidate predictors were variables with P < 0.05 in bivariate models. RESULTS: Anemia prevalence was 18.6% (95% CI: 15.8, 21.4). MNP intake [adjusted OR (AOR): 0.25, 95% CI: 0.07, 0.86], log (ln) ferritin (µg/L) (AOR: 0.49, 95% CI: 0.38, 0.64), and ln RBP (µmol/L) (AOR: 0.42, 95% CI: 0.18, 0.95) were associated with reduced odds of anemia. Younger age (6-23 mo compared with 24-59 mo; AOR: 2.29, 95% CI: 1.52, 3.46), other Terai ethnicities (AOR: 2.59, 95% CI: 1.25, 5.35) and Muslim ethnicities (AOR: 3.15, 95% CI: 1.30, 7.65) relative to Brahmin/Chhetri ethnicities, recent fever (AOR: 1.68, 95% CI: 1.08, 2.59), ln C-reactive protein (mg/L) (AOR: 1.23, 95% CI: 1.03, 1.45), and glucose-6-phosphate dehydrogenase deficiency (AOR: 2.84, 95% CI: 1.88, 4.30) were associated with increased odds of anemia. CONCLUSION: Both nonmodifiable and potentially modifiable factors were associated with anemia. Thus some but not all anemia might be addressed through effective public health policy, programs, and delivery of nutrition and infection prevention and control.

RESUMO

Background & objectives: The haemoglobin (Hb) cut-off is a single value for all populations. It is possible that different populations might have slightly different cut-off values; but, this needs to be evaluated in healthy populations with low possibility of inadequate dietary intakes of haematopoietic nutrients. This study was conducted to assess the existence of race-specific Hb cut-offs for mild anaemia in healthy populations and their potential implications. Methods: In this study the Hb distributions of healthy White, Black, Mexican and Hispanic and Asian non-pregnant women obtained from nine rounds of the National Health and Nutrition Examination Survey (NHANES) and two rounds of National Diet and Nutrition Survey (NDNS), was examined to check the existence of race-specific Hb cut-off for mild anaemia, by standard statistical methods. Results: The mean Hb of Blacks, Mexicans and Hispanics and Asians were lower than Whites, consistent with previous literature. The Hb cut-off for mild anaemia in Asians was lower at 11.22 g/dl. Interpretation & conclusions: Using the Hb cut-off derived in this study in place of the World Health Organization, cut-off of 12 g/dl would result in a 17.9 per cent decrease in the prevalence of anaemia in India. This points to the need for re-examining race-specific cut-off for mild anaemia and points to the need for alternative methods, perhaps linked to risk of unhealthy outcomes.

RESUMO

BACKGROUND: The Bedouins living in southern Israel are a Muslim-Arab population that is transitioning from a nomadic lifestyle to life in permanent settlements. The population has unique characteristics that could affect hemoglobin A1c (HbA1c) measurements. The objective of this study was to describe the socio-demographic and unique morbidity characteristics of this community and their effect on HbA1c measurements. Consanguinity, especially among cousins in the Bedouin population, results in a high prevalence of autosomal recessive genetic diseases such as thalassemia (underestimate of HbA1c), hemoglobinopathies (underestimate and overestimate), Gilbert's disease, and glucose-6-phosphate dehydrogenase deficiency, an X-linked disorder, which can cause hyperbilirubinemia with an overestimate of HbA1c. Furthermore, nutritional deficiencies, autosomal recessive diseases, high birth rates, parasitic infections, and poverty can all cause high rates of anemia (iron and vitamin B12 deficiencies) that can raise HbA1c levels. Congenital dyserythropoietic anemia is found among Bedouin tribes in the Negev region and can lead to an underestimation of HbA1c levels. Pregnancy can also affect HbA1c levels. Medical teams working in the Bedouin community and in other Muslim populations with similar morbidity characteristics throughout the world should identify patients with medical conditions that can affect HbA1c measurements and be aware of possible measurement alternatives such as fructosamine and glycated albumin.

RESUMO

BACKGROUND: Anemia is a common cause among the elderly for increased mortality. Hemoglobin concentration can be affected by many factors, but the reference interval defined by the World Health Organization has not been adjusted for the previous half century. METHODS: Through using the dataset generated by the National Health Insurance (NHI) health screening program of Republic of Korea, here we attempt to present a close to actual hemoglobin concentration of the Korean population. Between January 2009 and December 2013, a total of 57,409,872 health screening events were registered in the NHI database. Following the exclusion criteria, 6,759,566 participants were enrolled for analyses. RESULTS: Significant portion of the study population was considered 'anemic', while the mean value (2.5% ~ 97.5%) of hemoglobin concentration from the study was 14.8 (12.5 ~ 16.8) g/dL in men and 12.8 (10.6 ~ 14.7) g/ dL in women. Concordant results of hemoglobin concentration declining with age were observed as previous studies have described, supporting the need for separate, possibly lower cutoff in the elderly. CONCLUSIONS: A considerable portion of the participants being categorized as anemia contests the accuracy of the current lower cutoff for anemia. From a large representative dataset, the need for adjustment to the lower cutoff for anemia is suggested.

RESUMO

In this study, 1 065 infants and young children aged 24 months below in ethnic minorities gathering in poor rural areas in poor rural areas of Liangshan Yi Autonomous Prefecture of Sichuan Province and Gannan Tibetan Autonomous Prefecture of Gansu Province were investigated for their anemia status from October to November 2014, and the association between anemia and the utilization of maternal and child health services was analyzed. The prevalence of anemia in this area was 52.68%(561/1 065). After the adjustment of socio-demographic characteristics of mothers and infants, compared with infants aged 2-5 months, Han ethnic group, and infants whose mother was not anemic, the OR(95%CI) values of infant anemia for infants aged 6-12 months, 13-8 months, 19-24 months, ethnic minorities group, and infants whose mother was anemic were 11.65 (7.09-19.14), 9.91 (5.99-16.38), 5.87 (3.39-10.16), 1.55 (1.10-2.18) and 1.52 (1.14-2.04), respectively; Compared with infants whose child examination times not up to standard, and who were not only non-hospital delivered but also received inadequate number of inoculation, the OR (95%CI) values of infant anemia for infants whose child examination times up to standard, and who were not only hospital delivered but also received adequate number of inoculation were 0.60 (0.38-0.94) and 0.71 (0.52-0.98), respectively. The infants anemia is associated with the utilization of maternal and child health services.

RESUMO

Objective: As anemia in pregnancy is associated with adverse perinatal outcomes, we sought to define the mean and the fifth percentile of Hb and Ht using a contemporary multiethnic large cohort of low-risk pregnancies, and assess potential racial differences. Methods: We conducted a retrospective cohort study on women who delivered between 1 January 2008 and 31 December 2013 in Reggio Emilia County, Italy. Linear mixed effects models were used to describe changes in mean Hb and Ht, while quantile regression with matrix-design bootstrap defined changes in the fifth percentile of Hb and Ht, controlling for race, maternal age, smoking, and pregnancy number. Results: We analyzed 23,657 hemograms from 7318 pregnancies and 6870 women. Multivariate analysis showed that when compared to Caucasians', African women's mean Hb and Ht were respectively 0.24 (95%CI 0.3-0.17) g/dl and 0.7 (95%CI 0.8-0.5) % lower, while Asian mothers' were 0.11 (95%CI 0.19-0.03) g/dl and 0.3 (95%CI 0.5-0.1) % inferior. Similarly, both African and Asian women had lower fifth Ht percentiles (-1, 95%CI -1.3 to -0.6, and -0.4, 95%CI -0.7 to -0.04) than Caucasians, while African mothers also had lower fifth Hb percentile (0.3, 95%CI 0.5-0.1). The fifth percentile for Hb and Ht were, respectively, 11.3 (95%CI 11-11.5) g/dl and 32.8 (95%CI 32.3-33.4) % in the first trimester, 10.4 (95%CI 10.1-10.6) g/dl and 30.2 (95%CI 29.6-30.8) % in the second trimester, 10.1 (95%CI 9.8-10.3) g/dl and 30.6 (95%CI 30-31.1) % in the third trimester. Conclusions: We provided contemporary references to define anemia in pregnancy, and we confirmed that even in pregnancy, African and Asian women have lower Hb and Ht than Caucasian. Racial and population-specific references may have significant clinical and public health implication for more accurate disease diagnosis and appropriate treatment.

RESUMO

Maternal anemia is a frequent problem during pregnancy, especially in developing countries, such as Pakistan. In this context, the present study was conducted to determine factors associated with maternal anemia prevalent among women of different age groups visiting different hospitals in Lahore from February to April 2017. The current study used a cross-sectional design involving 390 pregnant women. Data related to demographic area, maternal age, gestational age/period, educational and income level, as well as socioeconomic status of all the participants were collected. Also, hemoglobin levels of the participants were obtained for assessment of maternal anemia. A total of 57.7% of participants were anemic (34.4 % mild and 23.3% moderate anemia). Bivariate analysis showed that less education (p = 0.01), occupation as housewife (p = 0.03), lower income (p = 0.001), rural residence (p = 0.028), and greater number of house members (p = 0.04) were significantly associated with maternal anemia. Results of multivariable logistic regression showed that low income was the only significant factor independently associated with maternal anemia. These results suggest that interventions, such as the Nutrition Support Program, to improve nutritional status of pregnant women by providing free food supplements with focus on the poor and marginalized communities are recommended to prevent anemia.

RESUMO

BACKGROUND: Anemia is a major public health problem in Morocco especially among vulnerable groups including pregnant women. Several studies have confirmed that anemia is associated with demographic, socioeconomic and cultural factors. OBJECTIVE: The objective of this study is to describe the socioeconomic, cultural and demographic profile of a group of anemic pregnant women and to determine the conditions influencing the development of anemia in the Moroccan context. METHODS: A retrospective cross-sectional study was conducted by structured interview among a group of Moroccan pregnant women (300 of anemic women and 425 of non-anemic). Data were collected on biodemographic and socio-economic variables, the socio-cultural conditions of the women, the characteristics of the pregnancy and information relating to anemia. RESULTS: Using the WHO classification criterion according to the severity of anemia, 40.6%, 56.6% and 2.8% of anaemic women were respectively mildly, moderately and severely anemic. Primiparity, unemployment, lower socio-economic level and illiteracy, were found to be associated with the development of anemia in pregnant women. CONCLUSION: In Morocco, nutritional problems hamper human development and improvement of health status. Knowledge of the strictness of deficiencies and factors associated are necessary to develop adapted strategies intervention to the national context.
