The development of vaccines, antibiotics, and other preventive measures have contributed to the decrease in infectious diseases occurrence. This decline has opened ways to degenerative disease. Previous researches have indicated that lifestyle pattern is an independent contributor to the onset of chronic disease. Given that social isolation and loneliness contribute to depression, there is a likelihood that household type may be directly correlated to chronic disease occurrence and complications. Living arrangements have shifted from families with many people living in the same house and for a more extended period to single-person households where people live alone.
Single-person households are more likely to experience poor nutrition, isolation, limited social responsibilities, and decreased income. Inadequate nutrition in proteins and other vitamins worsen the health of the elderly population who live alone. Despite experiencing poor nutrition, studies showed that a single person spends more money on food than multiple people families. This article was designed (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8067825/) to address the nutritional difference between single and multiple person households, and suggest nutritional policies that can be implemented to improve the health of the geriatric population.
The majority of the geriatric population in rural areas live in single-person households and practice less physical exercise and lifestyle habits (smoking, drinking, obesity). Geriatric patients who live in single-person households are more likely to develop metabolic disease due to poor lifestyles and breakfast skipping. Excess sodium intake and low fiber worsen blood pressure and cardiovascular diseases. Breakfast skipping has a strong correlation to obesity, and most obese patients develop diabetes. In addition to income and employment as the causes of poor nutrition, a single-person household is also correlated to food insecurity and its complications.
