Sinar ultraviolet B adalah sumber utama vitamin D, tetapi wanita usia subur
yang bekerja di dalam ruangan mempunyai vitamin D yang rendah
meskipun Indonesia negara tropis. Tujuan penelitian ini untuk mengevalua-
si peranan paparan sinar matahari pada wanita usia subur terhadap status
vitamin D dan tekanan darah. Desain penelitian yang digunakan adalah
eksperimen tanpa kelompok kontrol pada 21 wanita sehat. Penelitian ini
membandingkan status vitamin D dan tekanan darah sebelum dan setelah
mendapat paparan sinar matahari pada wajah dan lengan tiga kali seming-
gu selama 12 minggu. Analisis data menggunakan uji t-berpasangan.
Paparan sinar matahari dapat meningkatkan vitamin D. Serum 25(OH)D
meningkat 15,9% dari 15.7 ng/dL menjadi 18,2 ng/dL. Paparan sinar mata-
hari menurunkan tekanan darah sistolik (nilai p = 0,004) dan diastolik (ni-
lai p = 0,011). Ultraviolet B dari sinar matahari 30 menit tiga kali seminggu
selama 12 minggu dapat memperbaiki status vitamin D dan tekanan darah.
Ultraviolet B sunlight exposure is a primary source of vitamin D, but women
of childbearing age who worked in room every day had low serum vitamin
D despite Indonesia is a tropical country. The objective of this study was to
evaluate the role of sun exposure in women of childbearing age on vitamin
D status, and blood pressure. An intervention before-after study without
group control was conducted on 21 healthy women. This study compared
vitamin D status, and blood pressure before and after receiving ultraviolet
B (UVB) from sun exposure on the face and both arms three times a week
for 12 weeks. Anthropometric parameter and blood pressure were mea-
sured, were determined at baseline and after 12 weeks of sun exposure.
The effect of sun exposure can improve vitamin D. Serum 25 (OH)D in-
crease 15.9% from 15.7 ng/dL to 18.2 ng/dL. Sun exposure significantly re-
duced systolic blood pressure (p value = 0.004), and diastolic blood pres-
