“…The younger group was observed to have lower HRQOL than the older group-a pattern that is not common when considering the previously published literature, in which aging was generally associated with impaired health, both physically and mentally [13,27,35,37]. However, others reported the opposite, with low-and middle-age groups reporting a persistent negative and worsening HRQOL [3,43]. A potential explanation for this contradictory result might be that younger people often bear a greater load, such as agricultural activities and daily labor, and are thus exposed to occupational health risk, which may cause lower HRQOL.…”
