Summary
A new scale, the Risk Factor Lifestyle Disorders Scale (RFLDS), effectively identifies adolescent risk factors for lifestyle disorders. This validated tool aids in early assessment and prevention, promoting better health outcomes.
Area of Science:
- Public Health
- Adolescent Health
- Scale Development
Background:
- Adolescents, though presumed healthy, are vulnerable to lifestyle disorder morbidities.
- Early management of risk factors impacting lifestyle disorders is crucial during adolescence.
Purpose of the Study:
- To develop and validate a scale for the quick and concise assessment of lifestyle disorder risk factors in adolescents.
Main Methods:
- Developed the Risk Factor Lifestyle Disorders Scale (RFLDS) based on literature review and expert consensus.
- Validated the scale using cross-sectional data from 1000 adolescents (16-18 years) via content, construct, and criterion validity.
- Employed Item Total Reliability, Exploratory Factor Analysis, Cronbach's Alpha, and Pearson's Correlation for analysis.
Main Results:
- The developed RFLDS scale comprises 19 items across seven factors: Socio-Economic Criteria, Nutritional Status, Body Composition, Low/High Risk Factor Foods, Mental Health/Family/Personal History, and Sleep/Physical Activity.
- Statistical validation included KMO=0.720, Bartlett's test p<0.0001, 64.75% variance explained, and Cronbach's alpha of 0.68.
Conclusions:
- The validated RFLDS provides a comprehensive and quick assessment tool for lifestyle disorder risk factors specifically in adolescents.
- RFLDS can serve as a screening tool in various settings to facilitate early intervention and prevention, contributing to improved adolescent well-being and WHO SDG 3.4.

01:26Longitudinal 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...
02:20Longitudinal Research
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...
01:18Factors Affecting Illness
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...

01:27Introduction to Stress and Lifestyle
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...
01:12Relative Risk
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
