Antenatal care is associated with adherence to iron supplementation among pregnant women in selected low-middle-income-countries of Asia, Africa, and Latin America & the Caribbean regions: Insights from Demographic and Health Surveys.

Anaemia is a global public health problem affecting 800 million women and children globally. Anaemia is associated with perinatal mortality, child morbidity and mortality, mental development, immune competence, susceptibility to lead poisoning and performance at work. The objective of this article is to identify whether antenatal care-seeking was associated with the uptake of iron supplementation among pregnant women, adjusting for a range of covariates. This article used data from the cross-sectional recent Demographic and Health Surveys (DHS) of 12 countries in Asia, Africa and Latin America & the Caribbean regions. The individual-level data from 273,144 women of reproductive age (15-49 years) were analysed from multi-country DHS. Multiple Logistic regression analyses were conducted using Predictive Analytics Software for Windows (PASW), Release 18.0. Receiving at least four antenatal care visits was significantly associated with the consumption of 90 or more iron-containing supplements in 12 low and middle income countries across three regions after adjusting for different household and respondent characteristics, while mass media exposure was found to be a significant predictor in India and Indonesia. Antenatal care seems to be the most important predictor of adherence to iron intake in the selected countries across Africa, Asia, Latin America and Caribbean regions.

Associations of Knowledge, Attitude, and Practices toward Anemia with Anemia Prevalence and Height-for-Age Z-Score among Indonesian Adolescent Girls.

BACKGROUND: Crucial gaps persist in knowledge, attitude, and practice (KAP) of adolescent girls that affect anemia and linear growth failure. OBJECTIVE: To understand the role of KAP as a risk factor of anemia and linear growth problem in adolescent girls. METHODS: We conducted a cross-sectional survey of 335 adolescent girls selected by clustered random sampling. The KAP questionnaire had 18 variables consisting of 9 knowledge, 3 attitude, and 6 practice components. Twelve variables addressed nutrition, dietary diversity, and health environments related to both anemia and stunting. The questionnaire was adapted from the 2014 Food and Agriculture Organization nutrition-related KAP guidelines for anemia. Dietary practice was evaluated from 2-day 24-hour recalls and a semi-quantitative food-frequency questionnaire. Associations between KAP and anemia, and height-for-age z-score (HAZ), were analyzed using multivariate logistic and linear regression models, respectively. RESULTS: The mean hemoglobin (Hb) level was 119.7 g/L, with 44% of the adolescent girls being anemic (Hb < 120 g/L) and mean height was 151.0 cm with 25% being stunted (HAZ < -2 standard deviation [SD]). The median KAP score was 7 and ranged from 3 to 10. Low to moderate KAP scores were not significantly associated with being anemic (adjusted odds ratio [AOR] = 1.26; P = .43), however 1-point KAP score increment was associated with an increase of HAZ by 0.037 SD (P = .012). CONCLUSIONS: The KAP related to diet and healthy environments was not associated with anemia prevalence, but was positively associated with increased HAZ among adolescent girls. Strategy to reduce anemia risk in this population should combine KAP improvement with other known effective nutrition interventions.

Zinc and vitamin A supplementation fails to reduce sputum conversion time in severely malnourished pulmonary tuberculosis patients in Indonesia.

BACKGROUND: A previous study showed that combination of zinc and vitamin A reduced sputum conversion time in pulmonary tuberculosis (TB) patients. OBJECTIVE: We studied the efficacy of which single micronutrient contributed more to the sputum conversion time. METHODS: In a double-blind randomized community trial, newly sputum smear positive pulmonary TB patients were assigned randomly to receive zinc, vitamin A, zinc + vitamin A or placebo on top of TB treatment. Patients were asked to deliver their sputum on weekly basis to measure positivity of the bacteria. Nutritional status, chest x-ray, hemoglobin, C-reactive protein (CRP), retinol and zinc level were examined prior to, after 2 and 6 months of treatment. RESULTS: Initially, 300 patients were enrolled, and 255 finished the treatment. Most patients were severely malnourished (mean BMI 16.5 ± 2.2 Kg/m2). Patients in the zinc + vitamin A group showed earlier sputum conversion time (mean 1.9 weeks) compared with that in the other groups; however the difference was not significant. Also, no benefit could be demonstrated of any of the used supplementations on clinical, nutritional, chest x-ray, or laboratory findings. CONCLUSIONS: This study among severely malnourished TB patients, did not confirm that single or combined supplementation of zinc and vitamin A significantly reduced sputum conversion time or had other significant benefit.

Associations of meal patterning, dietary quality and diversity with anemia and overweight-obesity among Indonesian school-going adolescent girls in West Java.

BACKGROUND: Poor diet is a risk factor for anemia, overweight, and obesity among adolescent girls. However, comprehensive assessment on dietary quality and habits in this population is limited. We assessed the association of meal patterning, dietary quality, and dietary diversity with both anemia and overweight-obesity. METHODS: We conducted a cross-sectional survey in 335 school-going adolescent girls aged 12-19 years from three districts in West Java using multi-stage cluster sampling. Meal patterning, Dietary Quality Index for Adolescents (DQI-A), and Dietary Diversity Score (DDS) were determined using 2-day 24-h recall. RESULTS: Of the girls, 45% were anemic and 17% overweight or obese. Eating occasions of 3-4 times (AOR 2.68, 95% CI 1.21-5.98) and >4 times (AOR 2.43, 95% CI 1.01-5.83) were associated with greater odds of developing anemia compared to eating occasions of <3 times. Adolescent girls who skipped dinner had greater odds of being overweight or obese (AOR 2.13, 95% CI 1.10-4.10) and were less likely to be anemic (AOR 0.56, 95%CI 0.33-0.95) compared to those who did not skip dinner. Difference in energy intake was found between girls who had dinner and skipped dinner (p = 0.05). Mean total DQI-A score was 44.4% ± 7.71% and DDS was 4.0 out of 9.0. DQI-A score was significantly higher in non-anemic compared to anemic girls. Moreover, each unit increment of 1% of total DQI-A score was associated with a 3.967 g/dL increases of hemoglobin after adjustment for confounders. We found differences in total DQI-A score between normal-weight and overweight or obese girls. DDS score was not significantly different between groups, although lower meat, chicken, and fish consumption were correlated with anemia (p<0.01). CONCLUSIONS: Overall, the girls had poor dietary quality and diversity. The findings therefore indicated the importance of improving dietary quality and diversity in a regular meal pattern, especially meal frequency and meal skipping, to reduce the risk of anemia and overweight-obesity among adolescent girls.

Efficacy of daily and weekly multiple micronutrient food-like tablets for the correction of iodine deficiency in Indonesian males aged 6-12 mo.

BACKGROUND: Infants are highly vulnerable to iodine deficiency, and little data exist on the effect of multiple micronutrient supplementation on their iodine status. OBJECTIVE: We aimed to compare the efficacy of daily and weekly multiple micronutrient food-like tablets (foodLETs) on increasing iodine status among infants. DESIGN: In a double-blind, placebo-controlled trial, 133 Indonesian males aged 6-12 mo were randomly assigned to 1 of 4 groups: a daily multiple-micronutrient foodLET providing the Recommended Nutrient Intake (RNI)(DMM), a weekly multiple-micronutrient foodLET providing twice the RNI (WMM), a daily 10-mg Fe foodLET (DI), or placebo. Urinary iodine (UI) concentrations were measured at baseline and at 23 wk. RESULTS: At baseline, the average UI concentration (1.37 micromol/L) was within the normal range, and 30.8% of subjects had iodine deficiency (UI < 0.79 micromol/L). At 23 wk, the DMM group had the highest increment in UI; however, after adjustment for initial UI, the changes in UI were not significantly different between the 4 groups (P = 0.39). Initial UI correlated inversely with the changes in UI (P < 0.001). The DMM group had the greatest reduction and increment in the proportion of iodine-deficient infants and in infants with iodine excess, respectively; however, no significant difference was found in these proportions (P = 0.13 and P = 0.42) between the 4 groups. CONCLUSION: Daily consumption of a multiple-micronutrient foodLET providing the RNI during infancy may be one strategy to improve iodine status.

Effect of daily or weekly multiple-micronutrient and iron foodlike tablets on body iron stores of Indonesian infants aged 6-12 mo: a double-blind, randomized, placebo-controlled trial.

BACKGROUND: There is still uncertainty about the best procedure to alleviate iron deficiency. Additionally more reliable methods are needed to assess the effect of iron intervention. OBJECTIVE: We examined the efficacy of daily iron (10 mg), daily and weekly multiple-micronutrient supplementation (10 and 20 mg Fe, respectively) in improving body iron stores of Indonesian infants. DESIGN: Infants aged 6-12 mo were randomly allocated to 1 of 4 groups: daily multiple-micronutrients (DMM) foodlike tablets (foodLETs), weekly multiple-micronutrient (WMM) foodLETs, daily iron (DI) foodLETs, or daily placebo. Hemoglobin, ferritin, transferrin receptors, and C-reactive protein data were obtained at baseline and 23 wk. RESULTS: Body iron estimated from the ratio of transferrin receptors to ferritin was analyzed for 244 infants. At baseline, mean iron stores (0.5 +/- 4.1 mg/kg) did not differ among the groups, and 45.5% infants had deficits in tissue iron (body iron < 0). At week 23, the group DI had the highest increment in mean body iron (4.0 mg/kg), followed by the DMM group (2.3 mg/kg; P < 0.001 for both). The iron stores in the WMM group did not change, whereas the mean body iron declined in the daily placebo group (-2.2 mg/kg; P < 0.001). Compared with the daily placebo group, the DMM group gained 4.55 mg Fe/kg, the DI group gained 6.23 mg Fe/kg (both P < 0.001), and the WMM group gained 2.54 mg Fe/kg (P = 0.001). CONCLUSIONS: When compliance can be ensured, DI and DMM foodLETs are efficacious in improving and WMM is efficacious in maintaining iron stores among Indonesian infants.

Knowledge and perception of tuberculosis and the risk to become treatment default among newly diagnosed pulmonary tuberculosis patients treated in primary health care, East Nusa Tenggara: a retrospective study.

BACKGROUND: Despite the high efficacy of tuberculosis (TB) drug regiments, one of the barriers in the TB control program is the non-compliance to treatment. Morbidity, mortality, and risk to become resistant to drugs are emerging among defaulters. Thus, the aim of this study is to identify the factors, especially knowledge and perceptions of TB and association with treatment default among patients treated in primary care settings, East Nusa Tenggara. METHODS: This study was part of a bigger cohort community-based controlled trial study. The subjects were newly diagnosed pulmonary TB patients from four districts in East Nusa Tenggara. Knowledge, perception of TB, and other related factors were assessed prior to the treatment. Patients who interrupted the treatment in two consecutive months were classified as defaulters, as World Health Organization stated. Odds ratio (OR) looking for factors associated with becoming defaulter was analyzed. RESULTS: A total of 300 patients were recruited for this study. At the end of the treatment, 255 patients (85%) completed the treatment without interruption from regular visit. In univariate analysis, none of the socio-demographic factors attributed to treatment default yet lack of knowledge and incorrect perception of TB prior therapy (OR 2.49 1.30-4.79 95% CI, p = 0.006; OR 5.40 2.64-11.04 95% CI, p < 0.001, respectively). In multivariate analysis, only incorrect perception of TB showed significant association with treatment default (OR 4.75 2.30-9.86 95% CI). CONCLUSIONS: Assessing the knowledge and perception of TB prior to the treatment in newly pulmonary TB patients is important as both of them were known as risk factor for treatment default. Education and counseling may be required to improve patients' compliance to treatment.

Effectiveness of the Bacillus Calmette-Guerin vaccine in an Indonesian population with D543N NRAMP1 polymorphism.

INTRODUCTION: Bacille Calmette-Guerin (BCG) vaccination remains a routine immunization in primary care in tuberculosis (TB)-endemic areas, though several studies found that its efficacy was inconclusive. Natural resistance-asociated machrophage protein 1 (NRAMP1) polymorphism has been shown to result in higher susceptibility to TB. Information on genetic susceptibility in populations will be useful in planning the application of the BCG vaccine. The present study explored BCG efficacy in a rural Timor population with specific NRAMP1 polymorphism in a TB-endemic region of eastern Indonesia. METHODOLOGY: A case-control study with 64 newly diagnosed pulmonary TB patients and 65 healthy controls was performed. BCG scars were examined by a physician. NRAMP1 polymorphism was evaluated using molecular methods. RESULTS: Half of the subjects (65; 50.4%) had a clear presenting BCG scar on the upper arm, suggesting a successful BCG vaccination. Among the subjects, D543N NRAMP1 polymorphism, history of contact with TB patients, and not having a clear BCG scar on the upper arm tended to be significantly association with active TB. The significant differences were more profound when subjects were divided based on presenting BCG scar. Subjects without clear BCG scars had significant association with developing TB disease (p = 0.014). In multivariate analysis, history of previous contact with TB patients and unclear presenting BCG scar were associated with active TB (OR 9.2; 2.0-43.8 95% CI, OR 4.8; 2.1-11.0 95% CI, respectively). CONCLUSIONS: BCG vaccination in our population was effective for TB protection, especially in highly endemic areas of TB, regardless genetic susceptibility.

Decreased plasma leptin concentrations in tuberculosis patients are associated with wasting and inflammation.

Tuberculosis patients often suffer from severe weight loss, which is considered to be immunosuppressive and a major determinant of severity and outcome of disease. Because leptin is involved in weight regulation and cellular immunity, its possible role in tuberculosis-associated wasting was investigated. In an urban clinic in Indonesia, plasma leptin concentrations, indicators of adipocyte mass, appetite, C-reactive protein (CRP), tuberculin reactivity, and cytokine response were measured in tuberculosis patients and healthy controls. Plasma leptin concentrations were lower in patients than in controls (615 vs. 2,550 ng/liter; P < 0.001). Multivariate regression analysis showed that body fat mass and inflammation were two independent factors determining plasma leptin concentrations; there was a positive correlation between fat and leptin, whereas, unexpectedly, leptin was inversely associated with CRP and tumor necrosis factor-alpha production. Concentrations of both CRP and leptin were independently associated with loss of appetite. Our results do not support the concept that weight loss in tuberculosis is caused by enhanced production of leptin. Rather, loss of body fat leads to low plasma leptin concentrations, and prolonged inflammation may further suppress leptin production. Because leptin is important for cell-mediated immunity, low leptin production during active tuberculosis may contribute to increased disease severity, especially in cachectic patients.

A double-blind, placebo-controlled study of vitamin A and zinc supplementation in persons with tuberculosis in Indonesia: effects on clinical response and nutritional status.

BACKGROUND: The results of cross-sectional studies indicate that micronutrient deficiencies are common in patients with tuberculosis. No published data exist on the effect of vitamin A and zinc supplementation on antituberculosis treatment. OBJECTIVE: Our goal was to investigate whether vitamin A and zinc supplementation increases the efficacy of antituberculosis treatment with respect to clinical response and nutritional status. DESIGN: In this double-blind, placebo-controlled trial, patients with newly diagnosed tuberculosis were divided into 2 groups. One group (n = 40) received 1500 retinol equivalents (5000 IU) vitamin A (as retinyl acetate) and 15 mg Zn (as zinc sulfate) daily for 6 mo (micronutrient group). The second group (n = 40) received a placebo. Both groups received the same antituberculosis treatment recommended by the World Health Organization. Clinical examinations, assessments of micronutrient status, and anthropometric measurements were carried out before and after 2 and 6 mo of antituberculosis treatment. RESULTS: At baseline, 64% of patients had a body mass index (in kg/m(2)) < 18.5, 32% had plasma retinol concentrations < 0.70 micromol/L, and 30% had plasma zinc concentrations < 10.7 micromol/L. After antituberculosis treatment, plasma zinc concentrations were not significantly different between groups. Plasma retinol concentrations were significantly higher in the micronutrient group than in the placebo group after 6 mo (P < 0.05). Sputum conversion (P < 0.05) and resolution of X-ray lesion area (P < 0.01) occurred earlier in the micronutrient group. CONCLUSION: Vitamin A and zinc supplementation improves the effect of tuberculosis medication after 2 mo of antituberculosis treatment and results in earlier sputum smear conversion.

IRIS. I: a FOODlet-based multiple-micronutrient intervention in 6- to 12-month-old infants at high risk of micronutrient malnutrition in four contrasting populations: description of a multicenter field trial.

Infants in developing countries are at risk of concurrent micronutrient deficiencies, because the same causative factors may lead to deficiencies of different micronutrients. Inadequate dietary intake is considered one of the major causes of micronutrient deficiencies, especially among poor and underprivileged children in developing countries. Operational strategies and distribution systems are often duplicated when supplementation programs for single micronutrients are implemented at the same time. The International Research on Infant Supplementation (IRIS) trial was conducted in four distinct populations on three continents: Africa, Latin America, and Asia. The participating countries were South Africa, Peru, Vietnam, and Indonesia. The study had a randomized, doubleblind, placebo-controlled design. Each country aimed to enroll at least 70 infants per intervention group (65 + 5 anticipated dropouts). The micronutrient vehicle was in the form of a "foodlet" (food-like tablet) manufactured as chewable tablets, which were easy to break and dissolve, and which had the same taste, color, and flavor for all countries. Children were randomly assigned to one of four 6-month intervention groups: group 1 received a daily foodlet containing multiple micronutrients; group 2 received a daily placebo foodlet containing no micronutrients; group 3 received a weekly foodlet that contained multiple micronutrients (twice the dose of the daily foodlet) and placebo foodlets on the other days of the week; group 4 received a daily foodlet containing only 10 mg of elemental iron. The IRIS Trial aimed to examine the prevalence of multi-micronutrient deficiencies in 6- to 12-month-old infants from rural populations, and to examine the efficacy of multi-micronutrient supplementation in infants from the different countries included in the study. This paper describes the general methodology of the IRIS trial and the operational differences among the country sites.

Cytokines related to nutritional status in patients with untreated pulmonary tuberculosis in Indonesia.

Although several studies have dealt with the patterns of cytokine production in tuberculosis, little is known about the association between nutrient deficiencies and cytokines in tuberculosis. The objective of this study was to assess the concentration of cytokines related to nutritional status during tuberculosis. In 41 untreated tuberculosis patients and matched healthy controls in an urban hospital in Indonesia, we measured: height and weight, parameters of iron, vitamin A and zinc; and cytokines concentrations in the circulation and production in whole blood cultures. Plasma interleukin-6 (IL-6) and interleukin-1 receptor antagonist (IL-1ra) were significantly higher in patients than in controls. Patients with cavities (n=26) had higher concentrations of IL-6 than patients without cavities (n=15). Body mass index <18.5 kg/m2 was associated with high concentrations of tumor necrosis factor-alpha (TNF-alpha) and IL-6. Anaemia was associated with high concentrations of IL-6 and IL-1ra. Zinc deficiency was associated with high LPS-stimulated production of TNF-alpha and IL-1ra. Marginal plasma retinol concentrations were associated with high concentrations of IL-6 after LPS stimulation. In conclusion, low concentrations of micronutrients in tuberculosis were associated with increased cytokine production. An intervention study would allow causality to be examined.

Multiple micronutrient supplements improve micronutrient status and anemia but not growth and morbidity of Indonesian infants: a randomized, double-blind, placebo-controlled trial.

Multiple micronutrient deficiencies are highly prevalent in Indonesia, but the interventions are still focused on single micronutrients. This study aimed to investigate the efficacy of multiple micronutrient supplements for improving micronutrient status, anemia, growth, and morbidity of Indonesian infants. In this double-blind, placebo-controlled trial, 284 infants aged 6-12 mo were randomly allocated to 4 treatment groups for 23 wk; 260 (92%) infants completed the study. Group 1 (DMM) received one adequate intake of multiple micronutrient supplements daily (n = 66); group 2 (WMM) received 2 adequate intakes of multiple micronutrient on 1d plus 6 d of placebo (n = 60); group 3 (DI) received 10 mg of iron supplement daily (n = 69); group 4 received a placebo supplement daily (n = 65). Blood samples were collected at baseline and at posttreatment to assess anemia and micronutrient status. Anthropometric measurements were taken monthly, and morbidity was recorded daily. At baseline, 58.1% of infants were anemic, 34.2% were iron deficient, 21.3% were vitamin A deficient, and 11% were zinc deficient. The DMM and DI supplements both corrected iron deficiency, but DMM supplements were more efficacious in improving hemoglobin levels of anemic infants than the other supplements. However, anemia still persisted in one-third of DMM infants posttreatment. The DMM supplement was more efficacious than WMM or DI supplementation in improving infant status of other micronutrients, including zinc, tocopherol, and riboflavin, whereas DI exacerbated zinc deficiency. There were no significant differences in growth and morbidity among treatment groups, and growth faltering was not prevented.

Efficacy of a foodlet-based multiple micronutrient supplement for preventing growth faltering, anemia, and micronutrient deficiency of infants: the four country IRIS trial pooled data analysis.

Diets of infants across the world are commonly deficient in multiple micronutrients during the period of growth faltering and dietary transition from milk to solid foods. A randomized placebo controlled trial was carried out in Indonesia, Peru, South Africa, and Vietnam, using a common protocol to investigate whether improving status for multiple micronutrients prevented growth faltering and anemia during infancy. The results of the pooled data analysis of the 4 countries for growth, anemia, and micronutrient status are reported. A total of 1134 infants were randomized to 4 treatment groups, with 283 receiving a daily placebo (P), 283 receiving a weekly multiple micronutrient supplement (WMM), 280 received a daily multiple micronutrient (DMM) supplement, and 288 received daily iron (DI) supplements. The DMM group had a significantly greater weight gain, growing at an average rate of 207 g/mo compared with 192 g/mo for the WMM group, and 186 g/mo for the DI and P groups. There were no differences in height gain. DMM was also the most effective treatment for controlling anemia and iron deficiency, besides improving zinc, retinol, tocopherol, and riboflavin status. DI supplementation alone increased zinc deficiency. The prevalence of multiple micronutrient deficiencies at baseline was high, with anemia affecting the majority, and was not fully controlled even after 6 mo of supplementation. These positive results indicate the need for larger effectiveness trials to examine how to deliver supplements at the program scale and to estimate cost benefits. Consideration should also be given to increasing the dosages of micronutrients being delivered in the foodlets.
