Limitation of present epidemiological study is small sample size. Other shortcomings are: (i) Retrospective examination of a clinical phenomenon, (ii) point estimation of risk factors, which cannot prove a causal association, (iii) and the inferences observed are always non confirmatory in nature; thus these studies have lowest evidence level in evidence hierarchy.[43] This is a known inherent weakness of a cross-sectional study. In addition, present work is only an observational study and a suitable diet and life style intervention program could have provided rigid outcomes to health sector.
