“…In humans, this appears to be the case for ischaemic heart disease, diabetes mellitus and hypertension (Barker, 1993). It appears likely to apply to bone also as we, and others, have previously reported early life associations with smoking in utero and breast-feeding in early life (Jones et al, 2000a,b;Backstrom et al, 1999) as well as breast milk supplementation, although the bene®t reported at age 5 y did not persist at age 11 y (Bishop et al, 1996;Fewtrell et al, 1999). The dietary associations we report in this paper are independent of these factors and, unlike both breast-feeding and smoking, are present in both term and preterm infants, suggesting that they are not dependent on a possible physiology of maturity.…”

Maternal diet during pregnancy is associated with bone mineral density in children: a longitudinal study

Objective: To describe the association between maternal diet during the third trimester of pregnancy and bone mass in 8 y-old male and female children. Design: Longitudinal study. Setting: Southern Tasmania between 1988 and 1996. Subjects: One-hundred and seventy-three 8 -y-old male and female children with adequate maternal dietary information taking part in a study of bone mineralization. Results: After adjustment for confounders, femoral neck bone mineral density (BMD) was positively associated with magnesium and phosphorus density of the maternal diet; lumbar spine BMD was positively associated with magnesium, phosphorus and potassium and negatively associated with fat density while total body BMD was positively associated with magnesium, potassium and protein and negatively associated with fat density (all P`0.05). After further adjustment for other signi®cant dietary factors, the only signi®cant remaining associations observed were for phosphorus and fat at the lumbar spine, although the adjusted goodness of ®t of the models improved compared to those including one dietary variable. A child in the`optimal' levels of dietary exposures had signi®cantly higher adjusted BMD at all sites (femoral neck, 5.5%, lumbar spine, 12%, total body, 6.8%). Calcium intake was not associated with BMD at any site, possibly due to a high average intake. Conclusions: This study reports a substantial association between in utero diet in a well-nourished population and later bone mass in their children. However, it does not allow identi®cation of the dietary components of greatest importance, indicating that these results should be regarded as hypothesis-generating. Further longitudinal studies in other populations are required to con®rm that dietary manipulation during pregnancy has a role to play in the early life prevention of osteoporosis.

“…During the first year of life, several investigators report that the forearm bone mass of preterm infants is lower than that of term infants, 2,17,18 but the preterm child may resolve this difference in bone mineralization by 2 years of age. [18][19][20] However, another study of adolescents with a mean age of 15 years who were born at extremely low birth weight <1000 g reports significantly lower total body mineral content but not density compared with control adolescents. 13 Total bone mineral content is the measurement of the weight of hydroxapatite or calcium whereas bone density is the bone mineral content divided by the area.…”

Growth and bone mineralization in children born prematurely

et al. 2008

Objective: To study the growth and bone mineralization of children born prematurely.Study Design: A cohort of healthy children who were born prematurely with birth weight less than 1.5 kg were compared by weight and height to a national reference. Bone mineral status of preterm infants was compared with children who were born at term gestation. The average follow-up was 7 years. A sample of children who were born prematurely was recalled from an infant nutrition study. Children born at term gestation who had similar body weight for age were recruited from the community. Bone mineral evaluation was conducted in a group of 20 children born prematurely with birth weight less than 1.5 kg and in 15 children born at term gestation. Body weight for age was similar between the groups. All children were born of appropriate size for gestational age at birth. All children had their body weight and height measured. Comparisons for growth assessment status were made with the NHANES III database and published standards. Dietary intakes and food frequency were analyzed. The bone mineral status was measured at two sites, lumbar spine and distal third radius bone.Results: The average age was 7 years, with a range of 5 to 9 years. Compared with the reference population, children who were born prematurely on the average had lower weights, heights and body mass index. Preterm children had a lower lumbar bone mineral content than term children, 12.8 ± 3.0 and 14.7 ± 2.2 g cm À1 (P<0.05). The lumbar bone mineral density was lower in the preterm group than in the term group, 0.525±0.062 and 0.574±0.073 g cm À2 , respectively (P<0.04). Three of the preterm children had a history of fracture whereas none of the term children reported any fractures. Conclusion:Children who were born prematurely with birth weights less than 1.5 kg tend to be significantly smaller for age and have lower lumbar spinal bone mineral content and density compared with children born at term gestation.

“…Tal processo engloba a degradação e reabsorção de massa óssea existente e posterior deposição de novo material ósseo. A formação de massa óssea excede a reabsorção durante o período de crescimento, ou seja, durante a infância e juventude, estabilizando-se durante a fase adulta (BISHOP et al, 1996;GERRIOR et al, 1998).…”

“…As principais doenças relacionadas ao tecido ósseo incluem raquitismo e osteoporose (NATIONAL INSTITUTE OF HEALTH, 1994;BISHOP et al, 1996). O raquitismo é uma doença da infância, causada por distúrbios no metabolismo de cálcio em decorrência de desnutrição e conseqüente carência de vitamina D, manifestando-se por alterações e deformações no desenvolvimento do esqueleto do indivíduo (NATIONAL INSTITUTE OF HEALTH, 1994;BISHOP et al, 1996).…”
