Kinlessness, sole family survivorship, and the mental and physical health of U.S. older adults.

Among women, kinlessness was largely unrelated to health outcomes, only being associated with an increased rate of ADL/IADL difficulties.

• Data drawn from 191,146 person-waves from the 1998-2018 Health and Retirement Study
• Kinlessness defined as lacking both a spouse/partner and children (family of procreation)
• Kinlessness among women was not significantly associated with chronic conditions, self-rated poor health, or depressive symptoms
• Only ADL/IADL difficulties showed a significant association with kinlessness in women

Sole family survivorship was positively associated with women's ADL/IADL difficulties, self-rated poor health, and depressive symptoms.

• Sole family survivorship defined as lacking family of origin kin, including parents and siblings
• Sole family survivorship was associated with three of the four health outcomes examined in women
• Health outcomes assessed included chronic conditions, ADL/IADL limitations, self-rated poor health, and depressive symptoms
• This pattern suggests family of origin ties are particularly important for women's health in later life

Among men, kinlessness was not associated with worse health outcomes.

• Neither chronic conditions, ADL/IADL difficulties, self-rated poor health, nor depressive symptoms were significantly associated with kinlessness among men
• This finding held despite kinlessness representing the absence of both spouse/partner and children
• Results suggest men's health is not significantly burdened by lack of a family of procreation

Sole family survivorship was associated with more ADL/IADL difficulties and depressive symptoms among men.

• Among men, sole family survivorship was linked to two of the four health outcomes: ADL/IADL difficulties and depressive symptoms
• Sole family survivorship was not significantly associated with chronic conditions or self-rated poor health in men
• The pattern indicates that loss of family of origin kin has broader health implications than kinlessness for men

Social ties such as friends or nearby relatives were not uniformly protective of women's and men's health, calling into question the viability of substitutes for immediate family ties.

• The study examined whether substitution of friends or relatives nearby could mitigate health burdens of limited family ties
• Results indicated that social ties did not uniformly buffer against the health consequences of kinlessness or sole family survivorship
• Findings underscore the unique advantages of immediate family ties in later life
• This is interpreted in line with socioemotional selectivity theory, which posits that family ties play an increasingly salient role with age

Limited family ties are increasingly common among U.S. older adults, motivating the examination of two distinct forms: kinlessness and sole family survivorship.

• Kinless individuals lack a family of procreation (spouse/partner and children)
• Sole family survivors lack family of origin kin (parents and siblings)
• The study used 191,146 person-waves of data from the Health and Retirement Study spanning 1998–2018
• The authors note that prior research has not consistently examined these two forms of limited family ties separately

The study demonstrates that kinlessness and sole family survivorship have distinct ramifications for older adult well-being, with gender differences in which outcomes are affected.

• Kinlessness showed fewer and less consistent health associations compared to sole family survivorship across both sexes
• Sole family survivorship was more broadly associated with poor health outcomes for both women and men
• Gender moderated the pattern of associations, with women showing associations across more health domains for sole family survivorship
• The authors conclude that 'examining multiple forms of limited family ties' is important because they 'have distinct ramifications for older adult well-being'
