For studies of a similar design and which assessed the same outcomes in similar population groups , we report the potential for the combining of data across studies in systematic review s. CONCLUSIONS This scoping review has revealed the extensive evidence base for many outcomes which could be the focus of systematic review s exploring the health effects of conventional yogurt consumption
BACKGROUND The health effects of conventional yogurt have been investigated for over a century ; however , few systematic review s have been conducted to assess the extent of the health benefits of yogurt .
OBJECTIVE The aim of this scoping review was to assess the volume of available evidence on the health effects of conventional yogurt .
Intake of Dairy Products, Calcium, Magnesium, and Phosphorus in Childhood and Age at Menarche in the Tehran Lipid and Glucose Study
Purpose Studies indicate that milk intake is associated with insulin-like growth factor 1 ( IGF-1 ) concentrations and height in childhood , whether milk and other dairy products promote puberty remains unclear . This study aim ed to investigate influences of pre-pubertal intakes of milk , yogurt and cheese on menarcheal age in Tehranian girls . The associations of total dietary calcium ( Ca ) , magnesium ( Mg ) , and phosphorus ( P ) with menarcheal age were also examined . Methods This prospect i ve study was conducted on 134 pre-pubertal girls , aged 4 - 12 years at baseline , who participated in the Tehran Lipid and Glucose Study ( TLGS ) , and were followed for a median of 6.5 years .  Dietary intakes  were determined at initiation of the study using two non-consecutive 24-h dietary recalls and the age of menarche was documented during the follow-up . Logistic regression was used to calculate the risk of reaching menarche ≤ 12 years according to pre-pubertal levels of dairy or mineral intakes . Results The risk of earlier menarche was higher in girls with higher intakes of milk [ OR : 2.28 ( 95 % CI : 1.03–5.05 ) ] , Ca [ OR : 3.20 ( 95%CI : 1.39–7.42 ) ] , Mg [ OR : 2.43 ( 95 % CI : 1.12–5.27 ) ] and P [ OR : 3.37 ( 95 % CI : 1.44–7.87 ) after controlling for energy and protein intake , interval between the age at study initiation and the age of menarche , and maternal age at menarche ( Model 1 ) . Girls in the middle tertile of cheese intakes had a lower risk of reaching menarche ≤ 12 years than those in the lowest tertile after controlling for covariates in model 1 . These associations remained significant after further adjustment of BMI Z-score at baseline . The relationship of Ca , Mg , and P with menarche remained after further adjustment for height Z-score at baseline , whereas the association between milk and cheese intakes became non-significant . Conclusions Pre-pubertal intake of milk , but not cheese and yogurt , may hasten age at menarche
