Effect Of Different Feeding Types On The Bone Mineral Density Of Infants

Objective:In order to investigate the effect of different feeding types on the bone mineral density of infants aged 1 month,3 month and 6 month,this research has carried on questionnaire investigation to influential factors.Method:Bone mineral density of left midshaft tibia of 102 infants,aged 1 month,3 month and 6 month,,was measured with Aonuo ultrasound bone sonometer. Then the survey of its feeding types,whether added vitamin AD has been taken by means of questionnaire investigation and direct interview.The experimental data was processed by Statistical package with SPSS 11.5.Result:1.Aged 1 month,3 month,6 month, The BMD of infants with vitamin AD intake was 2795.5±14.6 (m/s),2826.3±13.6(m/s),2868.98±11.7(m/s); infants without vitamin AD intake was 2751.1±11.8(m/s),2770.5±11.9(m/s),2815.31±10.8(m/s). The BMD of infants with vitamin AD intake was significantly higher than infants without vitamin AD intake(P<0.05).2. Infants aged 1 month, the height of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 6.73±0.83kg,6.49±0.72kg,6.56±0.77kg; the weight of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 55.16±2.49cm,53.56±2.31cm,54.15±2.43cm. The height and weight of infants with pure breastfeeding was significantly higher than infants with artificial feeding and paretial dreast feeding(P<0.05).3.Infants aged 1 month, infants with vitamin AD intake:the BMD of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 2800.9±25.5(m/s),2750±22.0(m/s),2858.9±21.4(m/s); infants without vitamin AD intake:the BMD of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 2783.5±10.6(m/s),2658.2±19.1(m/s),2775.4±26(m/s). The BMD of infant with pure breastfeeding was significantly higher than infants artificial feeding (P<0.05).4.Infants aged 3 month, the height of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 6.73±0.83kg,6.49±0.72kg,6.56±0.77kg; the weight of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 63.48±3.38cm,62.11±2.22cm,62.26±2.33cm. The height and weight of infants with pure breastfeeding was significantly higher than infants with artificial feeding and paretial dreast feeding and paretial dreast feeding (P<0.05).5. Infants aged 3 month, infants with vitamin AD intake:the BMD of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 2896.7±30.1(m/s),2775.5±12.1(m/s),2833.5±21.1(m/s); infants without vitamin AD intake:the BMD of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 2797.6±11.7 (m/s),2681.5±22.6 (m/s),2804.2±22.0 (m/s).The BMD in infants with pure breastfeeding was significantly higher than infants with artificial feeding(P<0.05).6.Infants aged 6 month, the height of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 8.00±0.98kg,8.15±1.01kg,7.99±0.87kg; the weight of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 66.44±2.35cm,66.54±3.09cm 67.80±2.45cm. The height of infants with paretial dreast feeding was significantly higher than infants with pure breastfeeding and artificial feeding. The weight had no significant difference between pure breastfeeding,artificial feeding and paretial dreast feeding (P>0.05).7. Infants aged 6month, infants with vitamin AD intake:the BMD of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 2883.0±22.6 (m/s),2818.0±11.2 (m/s),2945.7±17.0 (m/s); infants without vitamin AD intake:the BMD of infants with pure breastfeeding,artificial feeding,paretial dreast feeding was 2807.4±13.5(m/s),2774.0±18.0 (m/s),2860.5±16.7 (m/s). The BMD in infants with paretial dreast feeding was significantly higher than infants with exclusive and artificial feeding(P<0.05).Conclusion:1.Aged 1 month,3 month,6 month, the BMD of infants with vitamin AD intake was significantly higher than infants without vitamin AD intake.2. Infants aged 1 month and 3 month,the physical growth of infants with pure breastfeeding was significantly higher than infants with artificial feeding and paretial dreast feeding; Infants aged 6month, The height of infants with paretial dreast feeding was significantly higher than infants with pure breastfeeding and artificial feeding. The weight had no significant difference between pure breastfeeding,artificial feeding and paretial dreast feeding.3.Infants aged 1 month and 3 month, the BMD in infants with pure breastfeeding was significantly higher than infants with artificial feeding.4. Infants aged 6month,The BMD in infants with paretial dreast feeding was significantly higher than infants with pure breastfeeding and artificial feeding.
