Assumptions of Survival Analysis01:15

Assumptions of Survival Analysis

Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.
The Nativist Approach01:21

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to exist...
Survival Tree01:19

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Survival Curves01:18

Survival Curves

Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.
The Kaplan-Meier estimator is the most common method for constructing survival curves. This...
Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

    Area of Science:

    • Demography
    • Public Health
    • Reproductive Health

    Background:

    • The child survival hypothesis posits that reduced child mortality increases family planning motivation and fertility decline.
    • Existing evidence on this relationship is drawn from diverse sources including vital statistics and program data.
    • Clarification is needed to accurately assess the hypothesis and its program implications.

    Purpose of the Study:

    • To review evidence on the relationship between infant and child mortality and fertility/contraceptive behavior.
    • To clarify the child survival hypothesis and its potential impact on family planning programs.
    • To identify factors influencing the link between child survival and fertility.

    Main Methods:

    • Review of time series data on vital events (local and national).
    • Analysis of in-depth studies on infant mortality-fertility relationships.
    • Examination of service statistics from health and family planning programs.

    Main Results:

    • The effect of improved child survival on fertility decline is not automatic or a necessary precondition.
    • Reduced inter-pregnancy intervals after child death are primarily due to the cessation of lactational amenorrhea.
    • A smaller, non-lactation-related effect on inter-pregnancy intervals also exists.
    • The impact is most significant in countries with rapid mortality decline and population growth.
    • Fertility replacement following child death is often subconscious rather than volitional.

    Conclusions:

    • Integrated maternal and child health and family planning services are crucial for program development.
    • Building parental confidence in health services can reinforce the mortality-fertility link.
    • Family planning services are more effective and acceptable when integrated with maternal and child health and nutrition.
