Answer: Young people who began drinking before age 15 were four times more likely to develop alcohol dependence (alcohol addiction, commonly known as alcoholism) than those who began drinking at age 21, researchers found.
Loneliness and social isolation have been linked with premature mortality and with functional decline in older people.
We found that high levels of loneliness, but not of social isolation, increased the risk of becoming physically frail.
Neither loneliness nor social isolation were associated with the rate of change in a more broadly defined frailty index.
Loneliness
Loneliness is a subjective feeling of dissatisfaction with one’s social relationships. Both social isolation and loneliness have been linked with increased mortality [2–4], incident heart disease [5, 6] and functional decline [7, 8]. Social isolation and loneliness tend to be correlated, albeit weakly .
Social isolation :
Social relationships are important for health . Most such research has focused on social isolation or loneliness. Social isolation is defined objectively using criteria such as having few contacts, little involvement in social activities and living alone.
Frailty :
Frailty is a clinical syndrome whose main feature is heightened vulnerability to stressors due to lowered physiological reserves, decline in the ability to maintain homeostasis and impairments in multiple systems
A frailty index score reflects the proportion of potential deficits present The phenotype model defines frailty in physical terms, whereas the cumulative deficit model uses a broader definition of frailty.
