Our results extend the Turkey study by using a multi-indicator model for defining ID, more sophisticated data analyses, and a much larger sample size (n = 5224 compared to 256).
Recently, some researchers have advocated the use of another multi-indicator model for iron status, "body iron", which yields a single parameter ranging from iron excess to iron deficit [ 47].
A final sensitivity analysis, for the indicator model, defined alcohol use for moderate drinkers only (>1 drink/day) in accordance with the 2010 Dietary Guidelines for Americans [ 23].
The best indicator semivariogram model for EC, SAR, Na+ and Cl− is often spherical and the best semivariogram model for HCO3 − and pH is exponential.
For the health-related pregnancy characteristics, we also adjusted for socioeconomic indicators (model 2) and also for the lifestyle characteristics (BMI; smoking) (model 3), to explore whether these explained any of the differences.
We derived estimates of means and standard errors for each indicator group, first controlling for differences in covariates across time points and practices within indicators (model 1), then adding control for differences between indicators (model 2).
More specifically, it described the trends of Health and Health related indicators, identified determinants of mortality and morbidity indicators and developed model for predicting future values of MDG indicators.
PON1 genotypes were examined categorically with two indicator variables per model: For PON1 −108, the CC genotype was the reference, and for PON1 192, the RR genotype was the reference.
Moreover, preliminary analysis suggested cessation searches increased around New Years; as a result, estimates for mean pre-, implementandon and post periods were made in absence of New Years effects by including additional indicators in the model for New Years wash-out periods (See Methods S1).
