Based on the search results, the National Family Health Survey (NFHS) 4 to NFHS 5 data shows the following changes in rural areas: 1. Infant Mortality Rate: There was an improvement in the infant mortality rate, as it decreased from 27.5 to 22 per 1,000 live births in rural areas. 2. Obesity in Women: The prevalence of obesity among women increased from 21% to 24% at the national level, indicating no improvement in this aspect. 3. Anaemia in Children: The prevalence of anaemia in children increased from 58.6% to 67%, indicating a worsening situation rather than an improvement. 4. Total Fertility Rate: The total fertility rate in rural areas improved, declining from 2.4 to 2.1 children per woman. Therefore, the correct option is 3, as anaemia in children did not show an improvement from NFHS 4 to NFHS 5 in rural areas.
