Many deliveries in low income countries still take place at home and the newborns are often not weighed. This community-based study ascertained the incidence of low birthweight (LBW) and compared the birthweight between home- and facility-born neonates in central Nepal. A total of 701 pregnant women from the Kaski district were recruited and interviewed. Birthweights of newborns were measured by pan balance in health facility settings immediately after birth, or by local community health volunteers using colour-coded spring balance within 48 h of home birth. Household follow up of participants were undertaken less than 45 days after delivery to record the weight of their infants. Of the 639 postpartum women who took part in the follow up interview, information on birthweight was available from 605 singleton births. Among them, 65 (10.7 %) were born at home. Overall, the mean birthweight was 3,059 (SD 464) g and incidence of LBW was 16.5 % (95 % CI 13.5-19.5 %). However, the home-born infants reported significantly lower (p = 0.009) mean birthweight (2,920, SD 435 g) than their facility-born counterparts (3,078, SD 461 g). This difference in birthweight remained significant (p = 0.03) after adjustment for maternal and socio-demographic characteristics. Incidence of LBW in central Nepal was quite high. Home-born babies appeared to have lower birthweight and thus their inclusion could provide an accurate estimate of the LBW rate.

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Confounding in Epidemiological Studies01:27

Confounding in Epidemiological Studies

Confounding in statistical epidemiology represents a pivotal challenge, referring to the distortion in the perceived relationship between an exposure and an outcome due to the presence of a third variable, known as a confounder. This variable is associated with both the exposure and the outcome but is not a direct link in their causal chain. Its presence can lead to erroneous interpretations of the exposure's effect, either exaggerating or underestimating the true association. This...

Study Designs in Epidemiology

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
