NEET BIOLOGY

Detailed explanation-1: -High infant mortality rates are generally indicative of unmet human health needs in sanitation, medical care, nutrition, and education. The infant mortality rate is an age-specific ratio used by epidemiologists, demographers, physicians, and social scientists to better understand the extent and causes of infant deaths.

Detailed explanation-2: -Preterm birth and low birth weight. Sudden infant death syndrome. Injuries (e.g., suffocation). Maternal pregnancy complications.

Detailed explanation-3: -The variables which show the highest disparity in mortality level are: natural region among the context variables, education of mother among the socioeconomic variables, and interbirth interval and maternal age at birth of their children among the biological ones.

Detailed explanation-4: -Rationale: Infant mortality represents an important component of under-five mortality. Like under-five mortality, infant mortality rates measure child survival. They also reflect the social, economic and environmental conditions in which children (and others in society) live, including their health care.

Detailed explanation-5: -The analysis considers biological correlates of mortality-mother’s age, birth order, birth interval, and previous infant loss-and several social factors-mother’s and father’s education, mother’s residence, father’s occupation, and mother’s work experience since marriage.
