Interactions of community nutritional status and xerophthalmia in Indonesia.

In order to determine which community level factors best explain the variation in the prevalence of xerophthalmia, an analysis was done on risk factors of xerophthalmia from the Indonesian Nutritional Blindness Study (1976 to 1979). Because of the common belief that xerophthalmia is closely linked to malnutrition, and the fact that within the study itself, it was demonstrated that children with xerophthalmia had a much higher prevalence of malnutrition than normal children, the relationship between the prevalence of malnutrition and the prevalence of xerophthalmia was explored. Using two different statistical approaches the prevalence of malnutrition within a community could not be demonstrated to be a good predictor of the prevalence of xerophthalmia within that community.

Vitamin A and vitamin E status of rural preschool children in West Java, Indonesia, and their response to oral doses of vitamin A and of vitamin E.

Vitamin A and E status was studied in five groups (satisfactory growth, reduced growth, night blindness, Bitot's spots, and corneal xerosis) of rural Indonesian preschool children. All groups except corneal xerosis showed satisfactory weight-height ratios. Initial serum retinol values were less than 0.35 mumol/L in 34% of all children. After oral administration of 24.4 mumol vitamin A, mean serum retinol values rose from 0.42 to 0.70 mumol/L at 10 d. After oral treatment of children with 244 or 314 mumol vitamin A, mean serum retinol remained greater than 0.56 mumol/L for 165 d. Of particular note were the low mean initial serum alpha-tocopherol concentrations (6.3 mumol/L) and alpha-tocopherol-total lipid ratios (1.5 mumol/g). Total serum lipids fell in the normal range. Oral administration of 84 mumol vitamin E raised serum alpha-tocopherol and alpha-tocopherol-total-lipid ratios by 46 and 44%, respectively. Thus, vitamin E inadequacy, which impairs vitamin A absorption and storage, may well contribute to the high incidence of clinical vitamin A deficiency in West Javan children.

Energy supplementation in the last trimester of pregnancy in East Java, Indonesia: effect on breast-milk output.

Breast-milk output was measured in women who during the last trimester of pregnancy consumed a high- or low-energy supplement (53 and 55 women, respectively). Infant and mother pairs were enrolled at 2 or 6 wk postpartum. Test weighings were done four times at 8-wk intervals. Mean breast-milk output ranged from 682 to 744 g/d in the age period of 2 wk to 7 mo. There was no difference in milk output between the two experimental groups. In all cohorts, breast-feeding frequency influenced milk output positively. Only at age 18-22 wk did the mothers' prepregnancy or 4-wk postpartum body mass index play an additional role. The results confirm that breast-milk output of mildly undernourished women is comparable with that of well-nourished women. Short-term energy supplementation during pregnancy did not increase breast-milk output, probably because the sample studied was not at nutritional risk.

Energy supplementation in the last trimester of pregnancy in East Java, Indonesia: effect on maternal anthropometry.

The effect of prenatal energy supplementation on maternal anthropometry was assessed in a controlled, randomized trial in Madura, East Java. At 26-28 wk of gestation women were either given 465 kcal/d (HE group) or 52 kcal/d (LE group). Two hundred seventy-six women were enrolled in the HE group and 266 women, in the LE group. Supplement intake was variable. Testing of effect by treatment and compliance was thus done by subcategories (HE 1-3 and LE 1-3, corresponding to less than 45, 45-89, and greater than or equal to 90 packets of supplement consumed). Analysis of variance did not show significant differences among the six subcategories in third-trimester weight gain, sum of skinfold thicknesses, 4-wk postpartum weight, or body mass index. In this population energy supplementation for the short duration of the last 90-110 d of pregnancy was not sufficient to improve maternal nutrition as judged by anthropometry.

Nutritional and household risk factors for xerophthalmia in Aceh, Indonesia: a case-control study. The Aceh Study Group.

Risk factors for xerophthalmia were assessed in 466 subjects [38% with night blindness (XN), 60% with Bitot's spots (X1B), 2% with corneal xerophthalmia (X2 or X3)] under age 6 y and their village-age-sex-matched control subjects during a community trial. Socioeconomic status and hygiene standards were lowest for households of xerophthalmic children and highest for nonstudy households in the trial population, with values for control households lying in between (P less than 0.001 by linear trend). Risk of xerophthalmia increased with less frequent consumption of dark green leaves, yellow fruits, or egg during weaning, adjusted for current intake and present age [odds ratio (OR) = approximately 3.5]. Exclusion of these same foods from the current diet (except for mango and papaya in older children) was associated with a two- to ninefold excess risk of xerophthalmia, adjusted for weaning influences. Xerophthalmic children aged less than 3 y were generally at higher risk of dietary imbalance than were older children. Xerophthalmia is associated with a chronic, infrequent consumption of key vitamin A foods from weaning through early childhood.

Bioefficacy of beta-carotene dissolved in oil studied in children in Indonesia.

BACKGROUND: More information on the bioefficacy of carotenoids in foods ingested by humans is needed. OBJECTIVE: We aimed to measure the time required for isotopic enrichment of beta-carotene and retinol in serum to reach a plateau, the extent of conversion of beta-carotene dissolved in oil with use of beta-carotene and retinol specifically labeled with 10 (13)C atoms, and the intraindividual variation in response. DESIGN: Indonesian children aged 8--11 y (n = 35) consumed 2 capsules/d, 7 d/wk, for < or =10 wk. Each capsule contained 80 microg [12,13,14,15,20,12',13',14',15',20'-(13)C(10)]beta-carotene and 80 microg [8,9,10,11,12,13,14,15,19,20-(13)C(10)]retinyl palmitate. Three blood samples were drawn per child over a period of < or =10 wk. HPLC coupled with atmospheric pressure chemical ionization liquid chromatography-mass spectrometry was used to measure the isotopic enrichment in serum of retinol with [(13)C(5)]retinol and [(13)C(10)]retinol and of beta-carotene with [(13)C(10)]beta-carotene. The beta-carotene in the capsules used had a cis-trans ratio of 3:1. RESULTS: Plateau isotopic enrichment was reached by day 21. The amount of beta-carotene in oil required to form 1 microg retinol was 2.4 microg (95% CI: 2.1, 2.7). The amount of all-trans-beta-carotene required to form 1 microg retinol may be lower. CONCLUSIONS: The efficiency of conversion of this beta-carotene in oil was 27% better than that estimated previously (1.0 microg retinol from 3.3 microg beta-carotene with an unknown cis-trans ratio). The method described can be extended to measure the bioefficacy of carotenoids in foods with high precision, requiring fewer subjects than other methods.

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.

Polio and lameness in Yogyakarta, Indonesia.

This survey for residual paralysis among rural and urban children in Central Java shows an overall rate for polio lameness of 9/10 000 children. A recent rise in reported cases of acute poliomyelitis is reflected in paralysis rate among preschool children of 22/10 000. Three quarters of cases occur before the third birthday. A majority of children below age 3 are lacking antibody titres to one or more types of polio virus, demonstrating the need for mass immunisation. A simple questionnaire detected polio cases with a sensitivity of 84%.

The Kintamani dog: genetic profile of an emerging breed from Bali, Indonesia.

The Kintamani dog is an evolving breed indigenous to the Kintamani region of Bali. Kintamani dogs cohabitate with feral Bali street dogs, although folklore has the breed originating 600 years ago from a Chinese Chow Chow. The physical and personality characteristics of the Kintamani dog make it a popular pet for the Balinese, and efforts are currently under way to have the dog accepted by the Federation Cynologique Internationale as a recognized breed. To study the genetic background of the Kintamani dog, 31 highly polymorphic short tandem repeat markers were analyzed in Kintamani dogs, Bali street dogs, Australian dingoes, and nine American Kennel Club (AKC) recognized breeds of Asian or European origin. The Kintamani dog was identical to the Bali street dog at all but three loci. The Bali street dog and Kintamani dog were most closely aligned with the Australian dingo and distantly related to AKC recognized breeds of Asian but not European origin. Therefore, the Kintamani dog has evolved from Balinese feral dogs with little loss of genetic diversity.
