The correlation between physical performance and vitamin C intake. = Korelasi antara kinerja fisik dan asupan vitamin C.

Undernutrition remains the most devastating problems facing the majority of the Indonesian, especially for the poor. Micronutrient malnutrition is believed to impair physical and cognitive development. Vitamin C deficiency has long been happening in Indonesia but was not detected. Vitamin C as an antioxidant is believed has beneficial effects on physical performance of children. This study aimed to evaluate the correlation between physical performance and vitamin C intake. This is a cross sectional study 209 undernourished subjects aged 7-9 years, 100 males and 109 females attending elementary schools in Jakarta, Indonesia were recruited in the study. Physical performance was assessed using Modified Harvard step test. The dietary intake of vitamin C was measured with three days dietary record and 24 hours dietary recall. The correlation between physical performance and vitamin C intake was assessed using spearman‟s correlation and statistical analyses were performed using SPSS for windows software version 18.0. Subjects were 48% male and 52% female and 146 children (70%) had a vitamin C level < 35mg/day. For physical performance 76 subjects (35.9%) had duration of step test < 60 seconds and half of the population‟s step test score was below 50th percentile (P50 = 7140). The mean fitness level and vitamin C intake did not differ by gender. There was a weak correlation between duration of step test and step test score and vitamin C intake with (r = 0.155, p = 0.025) and (r = 0.145, p = 0.037), respectively. These findings indicate that physical performance weakly correlated with vitamin C intake among undernourished children. These study population has an overall poor physical performance level and vitamin C deficiency based on the dietary intake.

Kekurangan gizi tetap masalah yang paling dahsyat yang dihadapi sebagian besar Indonesia, khususnya bagi masyarakat miskin. Malnutrisi mikronutrien diyakini mengganggu perkembangan fisik dan kognitif. Kekurangan vitamin C telah lama terjadi di Indonesia tetapi tidak terdeteksi. Vitamin C sebagai antioksidan dipercaya memiliki efek menguntungkan pada kinerja fisik anak. Penelitian ini bertujuan untuk mengevaluasi korelasi antara kinerja fisik dan asupan vitamin C.

Kinerja fisik dinilai menggunakan tes selangkah Harvard. Asupanmakanan vitamin C diukur dengan tiga catatan hari diet dan 24 jam ingat diet. Korelasiantara kinerja fisik dan asupan vitamin C dinilai menggunakan korelasi Spearman dan analisis statistik dilakukan dengan menggunakan SPSS untuk versi perangkat lunakwindows 18,0. Subjek 48% laki- laki dan perempuan 52% dan 146 anak (70%) memilikitingkat vitamin C < 35mg/ hari Untuk kinerja fisik 76 subyek (35,9%) memiliki durasi tes selangkah < 60 detik dan setengah dari skor tes penduduk langkah di bawah persentil 50 (P50 = 7.140). Tingkat kebugaran rata-rata dan asupan vitamin C tidak berbeda berdasarkan gender. Ada korelasi yang lemah antara durasi dari tes langkah dan langkah skor tes dan asupan vitamin C dengan (r = 0,155, p = 0,025) dan (r = 0,145, p =0,037), masing-masing. Temuan ini menunjukkan bahwa kinerja fisik lemah berkorelasi dengan asupan vitamin C antara anak-anak kurang gizi.
