Longitudinal Research02:20

Longitudinal Research

13.4K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

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...

Conservation of Small Populations02:04

Conservation of Small Populations

17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Population Growth00:57

Population Growth

28.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

What is Population Genetics?01:25

What is Population Genetics?

64.8K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Summary

Obesity, smoking, and strenuous work increase the risk of low back pain (LBP) and lumbar radicular pain. Leisure-time physical activity like walking or cycling may help prevent LBP, especially for those not exposed to physical workload factors.

Area of Science:

  • Epidemiology
  • Occupational Health
  • Public Health

Background:

  • Low back pain (LBP) and lumbar radicular pain are prevalent conditions with significant public health implications.
  • Identifying modifiable risk factors is crucial for developing effective prevention strategies.

Purpose of the Study:

  • To identify risk factors for LBP and lumbar radicular pain.
  • To assess if obesity and workload modify the effect of leisure-time physical activity on LBP and lumbar radicular pain.

Main Methods:

  • Longitudinal study of a nationally representative sample of Finnish adults (n=3,505) aged ≥30 years.
  • Data collected over 11 years, assessing LBP and lumbar radicular pain duration (past 12 months).
  • Analysis included factors like obesity, smoking, physical workload, and leisure-time physical activity.

Main Results:

  • LBP and lumbar radicular pain were more common in women. LBP decreased with age, while lumbar radicular pain increased.
  • Abdominal obesity increased LBP risk; general obesity increased lumbar radicular pain risk.
  • Smoking, strenuous physical work, and vibrating tools increased pain risk. Walking/cycling to work reduced LBP risk, particularly for non-obese individuals without heavy physical workload exposure.

Conclusions:

  • Lifestyle factors (obesity, smoking) and physical workload significantly increase the risk of LBP and lumbar radicular pain.
  • Leisure-time physical activities, such as walking and cycling, demonstrate preventive potential for LBP.
