A randomized community trial was carried out in Aceh, Indonesia, 1982-1984, to assess the impact of semiannual vitamin A (VA) supplementation (60,000 micrograms RE) on preschool child growth: 229 villages were randomized to VA program and 221 to control status. One thousand thirty-two program and 980 control children aged 1-5 y were assessed and followed for 12 mo. VA program males gained an additional approximately 110 g weight at age 2-3 y (NS), 190 g at age 4 y (p less than 0.05), and 263 g at age 5 y over control males (p less than 0.01). Arm circumference and muscle area expanded 2 mm (p less than 0.05) and approximately 36 mm2 (p less than 0.05) more per year, respectively, from ages 3 to 5 y of age and more arm fat was retained at every age (p less than 0.05 at 1 and 3 y) in VA males. There were no group differences in ponderal growth for females or in linear growth for either sex. VA supplementation may improve growth where endemic deficiency exists.

Mortality of Sumatran children living in villages randomized to participate in a vitamin A capsule (200,000 IU) distribution program who received the capsule (n = 9776) was compared with those who did not (n = 2447) and with children living in villages randomized to serve as control subjects (n = 12,173). During the 4 mo after completion of the first distribution, mortality among preschool capsule recipients was less than 4% that of nonrecipients (p less than 0.001). Mortality among preschool nonrecipients was three times that of controls (p less than 0.05), suggesting strong selection bias. The potential biologic impact on childhood mortality attributable to vitamin A supplementation is estimated to exceed the 34% previously derived from the more conservative intent-to-treat analysis. One capsule every 6 mo may provide adequate protection for the vast majority of children. The single major limitation to maximum impact appears to be inadequate program coverage.

Kesehatan mata sangatlah penting karena penglihatan tidak dapat digantikan dengan apapun, maka mata memerlukan pemeriksaan dan perawatan secara teratur. Penggunaan gadget pada masa sekarang sering kali digunakan untuk bermain games, interaksi social media, dan nonton video/film.  Membiarkan mata berinteraksi dengan gadget dengan durasi waktu yang lama akan menimbulkan risiko gangguan refraksi miopia, dampak lainnya akan mengalami kelelahan mata, pandangan kabur hingga sakit kepala yang muncul saat menggunakan gadget dengan durasi yang lama, hal inilah yang menyebabkan mata kering (Handrawan, 2014).  Untuk mengetahui Durasi Jarak dan Keluhan Kelelahan Mata yang ada pada pengguna gadget, tablet, atau laptop di Civitas Akademika STIKes Dharma Husada Bandung. Melalui pengisian kuesioner. Penelitian ini menggunakan metode survei deskriptif, dengan pendekatan cross sectional. Teknik pengambilan sampel adalah teknik purposive sampling dengan jumlah 258 responden. Penelitian ini dilakukan pada bulan Juli di Kampus STIKes Dharma Husada Bandung. Total sampel pada penelitian ini sebanyak 258 orang. Pada tabel distribusi Jarak, Durasi, dan Keluhan Kelelahan mata, diperoleh 93 orang (36%) menggunakan Gadget dengan jarak 20cm. sebanyak 138 orang (53%) menggunakan gadget dengan durasi >5 jam/Hari, dan sebanyak 236 orang (93%) mengalami Keluhan kelelahan mata. Pengetahuan penggunaan jarak dan durasi pada Civitas STIKes Dharma Husada Bandung masih kurang sehingga masih banyak yang mengalami keluhan kelelahan mata.
