Liver Cirrhosis, Etiology and Clinical Characteristics Disparities Among Minority Population

Liver cirrhosis (LC) is a common disease with varied primary causes and ethnic disparities. Clinical characteristics and outcomes of Arab Bedouin (AB) and Jewish patients with LC were retrospective collected and compared. We included 1048 patients, 95 (9%) Arab Bedouin and 953 (91%) Jewish patients. The incidence of cirrhosis was much lower among AB. Age at diagnosis was 47 ± 18 years among Bedouins compared to 61 ± 13 years (p < 0.001) among Jews. The most frequent causes of cirrhosis among Bedouin patients were fatty liver 21.1%, cryptogenic 20%, hepatitis B 17.9% and autoimmune hepatitis 15.8%, while hepatitis C (39.2%), fatty liver (17.2%) and alcoholic liver disease (14.4%) were most common among Jewish patients. An all-cause mortality of 48.4% was observed in AB patients compared to 66.4% in Jewish patients (p < 0.001). Significant disparities regarding incidence, clinical characteristics and outcomes of cirrhosis among Arab Bedouin compared with Jewish population were found.

Preconceptional diet quality is associated with birth outcomes among low socioeconomic status minority women in a high-income country

PURPOSE

Studies of the association between maternal nutrition and birth outcomes have investigated differing nutrients, maternal socioeconomic conditions, and timing within the reproductive cycle; and have produced inconsistent results. We evaluated the association of preconceptional maternal dietary intake with birth outcomes among low socioeconomic status ethnic minority women in a high-income country.

METHODS

In this prospective cohort study, habitual preconceptional dietary intake was assessed among pregnant Bedouin Arab women in Israel (n = 384), using a short culturally specific, targeted food frequency questionnaire. Multiple nutrients (protein, lysine, calcium, iron, zinc, folate, omega-3 fatty acids) were evaluated simultaneously via a diet quality score derived from principal component analysis. Multivariable logistic regression was used to test associations between the diet quality score and a composite adverse birth outcomes variable, including preterm birth, low birth weight and small for gestational age.

RESULTS

Sixty-nine women (18%) had adverse birth outcomes. Women with low preconceptional diet quality scores had low intakes of nutrient-rich plant foods, bioavailable micronutrients, and complete proteins. In multivariable analysis, a woman at the 10th percentile of the diet quality score had a 2.97 higher odds (95% CI 1.28-6.86) of an adverse birth outcome than a woman at the 90th percentile.

CONCLUSION

Low diet quality during the preconceptional period was associated with adverse birth outcomes among low socioeconomic status minority women in a high-income country. The results have implications for the development of appropriate intervention strategies to prevent adverse birth outcomes, and the promotion of adequate nutrition throughout the child-bearing years.

Sex effect on growth faltering in an indigenous ethnic minority population of infants in Israel

OBJECTIVE

We examined sex effects on growth faltering in an indigenous population of Bedouin Arab infants born in Israel, an economically developed country.

DESIGN

Retrospective cohort study. Height-for-age Z-score (HAZ) at age 6, 12, 18 and 24 months was calculated for full-term, normal-birth-weight Bedouin infants born during years 2000-2009 and attending maternal and child health (MCH) clinics. Multivariate linear regression analysis (MLRA) was used to calculate the association between sex and HAZ, controlling for year of birth, birth weight (BW) and residence by type of settlement (established settlement (ES); non-established settlement (NES)).

SETTING

Bedouin are an indigenous poor community of semi-nomadic Arabs, with the highest infant mortality rate in Israel. Fifty per cent of Bedouin infants live in NES with inadequate access to running water, electricity, and rubbish and sewage disposal. All Bedouin receive free well-baby care in community-based MCH clinics.

PARTICIPANTS

Full-term, normal Bedouin infants (n 5426) born during 2000-2009 and attending computerized MCH clinics who had growth measurements at age 6, 12, 18 and 24 months.

RESULTS

At all ages, girls had significantly higher mean HAZ than boys (P < 0·05). Increasing birth year, residence in ES and increasing BW were positively associated with HAZ (P < 0·05) at all ages. In MLRA controlling for birth year, BW and type of settlement, sex still had a significant effect, with lower HAZ among boys at 6, 12, 18 and 24 months of age (P < 0·001 at all ages).

CONCLUSIONS

Our results indicated that sex effects on growth faltering can occur in an indigenous population with low socio-economic status within an economically developed country.

Global inequities in dietary calcium intake during pregnancy: a systematic review and meta-analysis

BACKGROUND

Evidence shows that adequate calcium intake during pregnancy reduces the risk of hypertensive disorders of pregnancy. In most low- and middle-income countries (LMICs) the daily calcium intake is well below recommendations. Mapping calcium intake during pregnancy worldwide and identifying populations with low calcium intake will provide the evidence base for more targeted actions to improve calcium intake.

OBJECTIVE

To assess dietary calcium intake during pregnancy worldwide.

SEARCH STRATEGY

MEDLINE and EMBASE (from July 2004 to November 2017).

SELECTION CRITERIA

Cross-sectional, cohort, and intervention studies reporting calcium intake during pregnancy.

DATA COLLECTION AND ANALYSIS

Five reviewers working in pairs independently performed screening, extraction, and quality assessment. We reported summary measures of calcium intake and calculated the weighted arithmetic mean for high-income countries (HICs) and LMICs independently, and for geographic regions, among studies reporting country of recruitment, mean intake, and total number of participants. When available, inadequate intakes were reported.

MAIN RESULTS

From 1880 citations 105 works met the inclusion criteria, providing data for 73 958 women in 37 countries. The mean calcium intake was 948.3 mg/day (95% CI 872.1-1024.4 mg/day) for HICs and 647.6 mg/day (95% CI 568.7-726.5 mg/day) for LMICs. Calcium intakes below 800 mg/day were reported in five (29%) countries from HICs and in 14 (82%) countries from LMICs.

CONCLUSION

These results are consistent with a lack of improvement in calcium dietary intake during pregnancy and confirm the gap between HICs and LMICs, with alarmingly low intakes recorded for pregnant women in LMICs. From the public health perspective, in the absence of specific local data, calcium supplementation of pregnant women in these countries should be universal.

TWEETABLE ABSTRACT

Despite dietary recommendations, women in LMICs face pregnancy with diets low in calcium.

Variations in biochemical values for common laboratory tests: a comparison among multi-ethnic Israeli women cohort

BACKGROUND

Biochemical laboratory values are an essential tool in medical diagnosis, treatment, and follow-up; however, they are known to vary between populations. Establishment of ethnicity-adjusted reference values is recommended by health organizations.

AIM

To investigate the ethnicity element in biochemical lab values studying women of different ethnic groups.

METHODS

Biochemical lab values (n = 27) of 503 adult Israeli women of three ethnicities (Jewish Ashkenazi, Jewish Sephardic, and Bedouin Arab) attending a single medical center were analyzed. Biochemical data were extracted from medical center records. Ethnic differences of laboratory biochemicals were studied using ANCOVA to analyze the center of the distribution as well as quartile regression analysis to analyze the upper and lower limits, both done with an adjustment for age.

RESULTS

Significant ethnic differences were found in almost half (n = 12) of the biochemical laboratory tests. Ashkenazi Jews exhibited significantly higher mean values compared to Bedouins in most of the biochemical tests, including albumin, alkaline phosphatase, calcium, cholesterol, cholesterol LDL and HDL, cholesterol LDL calc., folic acid, globulin, and iron saturation, while the Bedouins exhibited the highest mean values in the creatinine and triglycerides. For most of these tests, Sephardic Jews exhibited biochemical mean levels in between the two other groups. Compared to Ashkenazi Jews, Sephardic Jews had a significant shift to lower values in cholesterol LDL.

CONCLUSIONS

Ethnic subpopulations have distinct distributions in biochemical laboratory test values, which should be taken into consideration in medical practice enabling precision medicine.

Maternal and child health in Israel: building lives

Israel is home to a child-oriented society that values strong family ties, universal child benefits, and free education for all children from 3 years of age to school grade 12. Alongside the universal health-care services that are guaranteed by the National Health Insurance Law and strong, community-based primary and preventive care services, these values have resulted in good maternal and child health. In 2015, infant and maternal mortality (3·1 deaths per 1000 livebirths and 2·0 deaths per 100 000 livebirths, respectively) were lower than the mean infant and maternal mortality of countries within the Organisation for Economic Co-operation and Development. Israel has already exceeded the developed regions' Sustainable Development Goal 2030 targets for maternal mortality, neonatal mortality, and mortality in children younger than 5 years in all population groups. Yet these accomplishments are marred by Israel's high prevalence of child poverty (more than 30%), particularly among Arabs (63%) and ultra-Orthodox Jews (67%). Although infant mortality has improved in all subpopulations since Israel was founded in 1948, infant mortality among Arabs is still more than twice as high as among Jews. To address these disparities in health, the Israeli Ministry of Health has created a special division and has funded an intervention programme to reduce the infant mortality among Bedouin Arabs. Other interventions include targeted and culturally appropriate health-care programmes and services for communities with a high number of at-risk children and young adults, dental health service for all children up to 15 years, and improved collaboration between health, education, and welfare services. The challenges faced by the Israeli health-care system include a growing trend towards medicalisation of prenatal care, ensuring staff are trained to treat developmental, behavioural, and psychosocial issues in children and their families, securing sustainable funding for health promotion and injury prevention programmes, expanding and improving the coordination of services for children with special needs or who are at risk, and programme assessment. Ensuring adequate funding for dedicated, preventive paediatric care and taking action on a nationwide scale to reduce child poverty are essential for maintaining health gains in children. In this Series paper, we describe the health indices, highlight disparities, and discuss the challenges in delivering and maintaining maternal and child health care in Israel.

Maternal pre-pregnancy BMI, gestational weight gain, and infant birth weight: A within-family analysis in the United States

In the United States, the high prevalence of unhealthy preconception body weight and inappropriate gestational weight gain among pregnant women is an important public health concern. However, the relationship among pre-pregnancy BMI, gestational weight gain, and newborn birth weight has not been well established. This study uses a very large dataset of sibling births and a within-family design to thoroughly address this issue. The baseline analysis controlling for mother fixed effects indicates maternal preconception overweight, preconception obesity, and excessive gestational weight gain significantly increase the risk of having a high birth weight baby, respectively, by 1.3, 3 and 3.9 percentage points, while underweight before pregnancy and inadequate gestational weight gain increase the low birth weight incidence by 1.4 and 2 percentage points. The benchmark results are robust in a variety of sensitivity checks. Since poor birth outcomes especially high birth weight and low birth weight have lasting adverse impacts on one's health, education, and socio-economic outcomes later in life, the findings of this research suggest promoting healthy weight among women before pregnancy and preventing inappropriate weight gain during pregnancy can generate significant intergenerational benefits.

Health and morbidity among Bedouin women in southern Israel: a descriptive literature review of the past two decades

In this paper we describe health and morbidity characteristics of Bedouin women in southern Israel, based on papers published over the past 20 years. This is a unique population whose customs, tradition, singular circumstances as a population "in transit", and underprivileged socio-economic status are reflected in mental illness, pregnancy course, perinatal morbidity and mortality rates, and acute and chronic disease. Recognition of these characteristics can help the medical team treat various health problems in this population as well as other populations with similar characteristics.

Literature review of type 2 diabetes mellitus among minority Muslim populations in Israel

This review surveys the literature published on the characteristics and implications of pre-diabetes and type 2 diabetes mellitus (T2DM) for the Arab and Bedouin populations of Israel. T2DM is a global health problem. The rapid rise in its prevalence in the Arab and Bedouin populations in Israel is responsible for their lower life expectancy compared to Israeli Jews. The increased prevalence of T2DM corresponds to increased rates of obesity in these populations. A major risk group is adult Arab women aged 55-64 years. In this group obesity reaches 70%. There are several genetic and nutritional explanations for this increase. We found high hospitalization rates for micro and macrovascular complications among diabetic patients of Arab and Bedouin origin. Despite the high prevalence of diabetes and its negative health implications, there is evidence that care and counseling relating to nutrition, physical activity and self-examination of the feet are unsatisfactory. Economic difficulties are frequently cited as the reason for inadequate medical care. Other proposed reasons include faith in traditional therapy and misconceptions about drugs and their side effects. In Israel, the quality indicators program is based on one of the world’s leading information systems and deals with the management of chronic diseases such as diabetes. The program’s baseline data pointed to health inequality between minority populations and the general population in several areas, including monitoring and control of diabetes. Based on these data, a pilot intervention program was planned, aimed at minority populations. This program led to a decrease in inequality and served as the basis for a broader, more comprehensive intervention that has entered the implementation stage. Interventions that were shown to be effective in other Arabic countries may serve as models for diabetes management in the Arab and Bedouin populations in Israel.
