More than a third of the U.S. population of older adults is obese. The present study tests the Dyadic Biopsychosocial Model of Marriage and Health, which hypothesizes that, among married couples, individual and partner chronic stress predicts increased waist circumference and these links are exacerbated in negative quality marriages.
Participants were from the nationally representative longitudinal Health and Retirement Study (HRS). A total of 2,042 married individuals (in 1,098 married couples) completed psychosocial and waist circumference assessments in 2006 and 2010. Analyses examined whether negative marital quality and chronic stress in Wave 1 (2006) were associated with changes in waist circumference over time.
Actor-partner interdependence models revealed that greater partner stress, rather than individuals' own reports of stress, was associated with increased waist circumference over time. Higher perceived negative marital quality among husbands and lower negative marital quality among wives exacerbated the positive link between partner stress and waist circumference.
Consistent with the Dyadic Biopsychosocial Model of Marriage and Health, partner stress has direct associations with waist circumference among couples and this link is moderated by negative marital quality. Thus, dyadic perceptions of stress and negative marital quality are important to consider for understanding marriage and obesity.
超过三分之一的美国老年人口肥胖。本研究检验了婚姻与健康的对偶生物心理社会模型，该模型假设在已婚夫妇中，个体和伴侣的慢性压力预示着腰围增加，而在负面质量的婚姻中，这些联系会加剧。
参与者来自具有全国代表性的纵向健康与退休研究（HRS）。共有 2042 对已婚夫妇（1098 对已婚夫妇）于 2006 年和 2010 年完成了心理社会和腰围评估。分析检验了第 1 波（2006 年）中负面婚姻质量和慢性压力是否与随时间推移腰围的变化有关。
演员-伴侣相互依存模型显示，伴侣的压力更大，而不是个体自己报告的压力，与随时间推移腰围的增加有关。丈夫感知到的负面婚姻质量较高，妻子感知到的负面婚姻质量较低，加剧了伴侣压力与腰围之间的正相关关系。
与婚姻与健康的对偶生物心理社会模型一致，伴侣压力与夫妇的腰围有直接关联，而这种关联受到负面婚姻质量的调节。因此，对于理解婚姻和肥胖，应考虑伴侣对压力和负面婚姻质量的看法。
