Lactation and fertility.

K Prema, A N Naidu, S N Kumari

    The American Journal of Clinical Nutrition
    |June 1, 1979

    Summary

    Despite a general trend of prolonged breastfeeding, urban women with better education and economic status showed shorter lactation durations. This may lead to shorter interpregnancy intervals, impacting maternal health.

    Area of Science:

    • Public Health
    • Maternal and Child Health
    • Reproductive Health

    Background:

    • Declining breastfeeding practices in urban areas of developing countries may negatively affect maternal and child health.
    • Breastfeeding plays a crucial role in infant nutrition and maternal-child well-being.

    Purpose of the Study:

    • To evaluate breastfeeding practices among urban hospital-attending women.
    • To investigate the relationship between breastfeeding duration, lactational amenorrhea, and interpregnancy interval.

    Main Methods:

    • A study involving 1079 urban hospital-attending women.
    • Data collection on breastfeeding duration, lactational amenorrhea, and interpregnancy intervals.

    Main Results:

    • Prolonged and successful lactation was common (mean duration 19.8 months; 3.5% failure).
    • A trend of shorter breastfeeding duration was observed in women with higher education and economic status.
    • Strong correlation found between lactation duration, lactational amenorrhea, and interpregnancy interval.

    Conclusions:

    • Decreased breastfeeding duration may result in shorter interpregnancy intervals.
    • Lactation duration appears fixed per individual, influencing lactational amenorrhea and interpregnancy intervals.
    • Breastfeeding offers limited protection against conception once menstruation resumes.
