Factors responsible for delayed immunisation among children under 5 years of age.

ABSTRACT

Although immunisation coverage has increased substantially in recent years, still a sizable proportion of children are not being immunised at appropriate time. The present hospital based, pair matched, case control study was carried out at immunoprophylactic centre of Government Medical College and Hospital, Nagpur, to identify risk factors associated with delayed immunisation among children. This study included 139 children with a delay of more than 90 days for scheduled primary immunisation and equal number of matched control (for dose) receiving immunisation at appropriate time. The study identified significant association of family size [Odd's ratio (OR) = 7.3, 95% confidence interval (CI) = 1.5-35.6], number of children < 5 years (OR = 3.17, 95% CI = 1.1-9.9), sex (OR = 3, 95% CI = 1.2-7.4), paternal education (OR = 3.7, 95% CI = 1.6-8.5), maternal education (OR = 4, 95% CI = 1.5-10.9), socio-economic status (OR = 3.7, 95% CI = 1.1-13.2) and distance from health centre (OR = 4.7, 95% CI = 1.2-17.6) with delayed immunisation. Negligence (56%) and unawareness (22.7%) of parents were main reasons for delayed immunisation. Hence more stress on identified risk factors in the study will indirectly help in reducing the frequency of delayed immunisation.
