Unemployment is an established risk factor for obesity. However, few studies have examined obesity-related health behavior after involuntary job loss specifically. Job loss confers a disruption in daily time structure that could lead to negative metabolic and psychological outcomes through chronobiological mechanisms. This study examines whether individuals with unstable social rhythms after involuntary job loss present with higher abdominal adiposity than individuals with more consistent social rhythms and whether this relationship varies as a function of depressive symptoms.
Cross-sectional baseline data ( = 191) from the ongoing Assessing Daily Activity Patterns in occupational Transitions (ADAPT) study were analyzed using linear regression techniques. Participants completed the Social Rhythm Metric-17 (SRM) daily over 2 weeks. They also completed the Beck Depression Inventory II (BDI-II) and participated in standardized waist circumference measurements (cm).
A significant interaction emerged between SRM and BDI-II demonstrating that less consistent social rhythms were associated with larger waist circumference at lower levels of depressive symptoms. Additional exploratory analyses demonstrated a positive association between the number of daily activities performed alone and waist circumference when controlling for symptoms of depression.
These findings are the first to demonstrate a relationship between social rhythm stability and abdominal adiposity in adults who have recently, involuntarily lost their jobs. Results highlight the moderating role of depressive symptoms on daily routine in studies of metabolic health. Future prospective analysis is necessary to examine causal pathways.
失业是肥胖的一个既定风险因素。然而，很少有研究专门考察非自愿失业后与肥胖相关的健康行为。失业会导致日常时间结构的紊乱，这可能通过生物钟机制导致负面的代谢和心理结果。本研究考察非自愿失业后社会节律不稳定的个体是否比社会节律更稳定的个体具有更高的腹部肥胖水平，以及这种关系是否因抑郁症状而有所不同。
使用线性回归技术分析了正在进行的职业转型中日常活动模式评估（ADAPT）研究的横断面基线数据（n = 191）。参与者在两周内每天完成社会节律量表-17（SRM）。他们还完成了贝克抑郁量表第二版（BDI-II），并参与了标准化腰围测量（厘米）。
SRM和BDI-II之间出现了显著的交互作用，表明在抑郁症状较轻的水平下，社会节律一致性较低与腰围较大有关。进一步的探索性分析表明，在控制抑郁症状时，单独进行的日常活动数量与腰围呈正相关。
这些发现首次证明了最近非自愿失业的成年人中社会节律稳定性与腹部肥胖之间的关系。结果突出了抑郁症状在代谢健康研究中对日常行为的调节作用。未来需要进行前瞻性分析以研究因果途径。
