    Fatty acid and, conjugated linoleic acid profiles of infant formulas through direct transesterification of acyl lipids
    (Chiriotti Editori, 2007) Tokusoglu, Oe.; Durucasu, I.; Akalin, A. S.; Serin, E.; Aksit, S.
    Fatty acid (FA) values, including C8:0, C10:0, C12:0, C13:0, C14:0, C16:0, C18:0, C18:1t, C18:1c, C18:2, C18:2 CLA, C20:0, C18:3 and C22:0, in sixteen infant formulas were determined through direct transesterification of acyl lipids with sodium methoxide by capillary gas chromatography. Total FA values ranged from 250.25-256.06 mg/g sample and the conjugated linoleic acid (CLA) (cis-9, trans-11 octadecadienoic acid) values were 1.41-2.02 mg/g sample (p < 0.01) in the infant formulas. The total saturated fatty acid, monounsaturated fatty acid and polyunsaturated fatty acid values were also obtained. The C18:3 (linolenic acid (n-3)) values were 0.63-0.88 mg/g sample, whereas the C18:2 (linoleic acid (n-6)) values ranged from 35.64-35.82 mg/g sample. FA standard mix including CLA had linear calibration curves through the origin (R-2 = 0.9999). The precision of the analytical method was (using C13:0, methyl tri-decanoate, as internal standard) within the 95% confidence limits and the mean recoveries determined for individual fatty acids in infant formulas varied from 99.8 to 100%.

    Vitamin D supplementation during the first two years of life in Izmir, Turkey
    (Edizioni Minerva Medica, 2014) Koc, F.; Halicioglu, O.; Sutcuoglu, S.; Akman, S. Asik; Aksit, S.
    Aim. The aim of the present study was to determine the prevalence of vitamin D supplementation and risk factors for non-supplemented infants in Izmir, Turkey. Methods. This cross-sectional study was carried out in Well-Child Care Clinics in Izmir, Turkey. Parents filled a questionnaire about socio-demographic characteristics and the use of vitamin D. SPSS version 16.0 was used for statistical analysis. Results. A total of 1002 children (aged 1 to 24 months) were enrolled in the study. The supplementation rates of vitamin D were 77% in the first 3 months of life, 57% at 10 to 12 months. Economic status of family, education of parents, occupational status of mothers and parity were associated factors with the use of vitamin D supplements in infants (P<0.05). However, when the data were analyzed using logistic regression analysis, only education of mother seems to be statistically significant independent variable in decreasing non-supplementation/ irregular supplementation. Conclusion. Vitamin D supplementation rates seem to be not satisfactory in Izmir. Therefore, the importance of vitamin D supplementation in infants should be emphasized in every well-child care visit to prevent vitamin D deficiency.
