Associations Between Romantic Relationship Factors and Body Mass Index Among Weight Loss Surgery Patients

Associations between marital status and weight loss trajectories entering into early adulthood: a Teen-LABS study

BACKGROUND

Among adolescents who underwent metabolic and bariatric surgery (MBS), it is unclear how relationships and specifically marital status (MS) may be associated with long-term weight loss.

OBJECTIVE

In this analysis, we tested for associations between the MS of adolescents who underwent MBS and the MS of their primary caregiver and weight loss trajectory over 8 years.

SETTING

Teen-LABS participating sites.

METHODS

This sample included 231 participants (75.3% female, 71.4% White, 68.0% Roux-en-Y gastric bypass, 27.7% vertical sleeve gastrectomy, 4.3% laparoscopic adjustable gastric band). A linear mixed model was conducted with the dependent variable percent body mass index (BMI) change from preoperatively through 8 years with between-participant factors (1) participant MS, (2) caregiver MS, and (3) interaction between caregiver and participant MS.

RESULTS

One third of participants and 87% of caregivers were ever married (EM). Compared with never-married (NM) participants and caregivers (-14.6%), EM participants and caregivers (-20.6%), EM participants and NM caregivers (-25.9%), and NM participants and EM caregivers (-19.8%), each had significantly greater BMI loss at 8 years (each P < .05). No other group comparisons achieved statistical significance.

CONCLUSIONS

NM participants with NM caregivers had less favorable long-term BMI. Additional research is needed to better understand how relationships affect behavior change and weight loss after MBS.

Impaired Family Functioning Affects 6-Month and 12-Month Postoperative Weight Loss

PURPOSE

Prior cross-sectional research details the high rate of impaired family functioning, a measure of the overall family environment, among adult bariatric surgery patients; however, family functioning has not been explored in relation to adult patient's postoperative outcomes. The objective of this study was to determine how family functioning affects postoperative patient outcomes including readmission rates, early complications, and 6- and 12-month percent total weight loss (%TWL).

MATERIALS AND METHODS

An observational design at a single-academic medical center was employed. The sample comprised 98 patients, living with ≥1 family member, who enrolled in one of two concurrent studies at the Center. Patients were followed from their surgical intake through 12 months postsurgery; family functioning was assessed within 2 months of their date of surgery. Chi-square and independent t tests determined significant associations between family functioning with readmission and complication rates. Average family functioning was an independent variable in multivariate linear regression models to determine significant correlates of %TWL at 6 and 12 months postsurgery. Patient age, race, and insurance status were included as covariates.

RESULTS

Patients with higher impaired family functioning had significantly less %TWL at 6 (p=.004) and 12 months (p=.030). Black patients also had significantly lower %TWL at 6 (p=.003) and 12 months (p=.009).

CONCLUSION

Family functioning and patient race were both correlates of weight loss at 6 months and 12 months. Future research should explore additional family factors as correlates of patient outcomes following bariatric surgery.

Family members' experiences with adult participation in weight management programs: Triadic perspectives from patients, partners and children

OBJECTIVE

Spouses are known to influence the outcomes of an individual's attempt at weight loss, but little is known about the broader influence of, and on, the family. The objectives were to explore: (a) the effects of an adult weight management program on the family and (b) family factors that help or hinder patient weight loss.

METHODS

A qualitative design was employed to explore triadic family members' experiences of patient participation in a weight management program. Semi-structured interviews were conducted with patients, partners and children (ages 7-18). Questions included support for patient participation and weight loss, dietary choices, meal preparation, physical activity routines, the home-food environment, communication about health and family dynamics. Thematic analysis was used, where codes and categories of codes were then grouped together to create themes and subthemes.

RESULTS

Nineteen triadic interviews were conducted (57 total). Seven themes emerged, including four related to Outcomes (objective 1): (a) shift in family dynamics, (b) family behaviour change, (c) child observations of family change, (d) indirect benefit to partner; and three related to Process (objective 2): (e) level of accountability, (f) patient perception of support and (g) support is essential and flexible.

CONCLUSIONS

Future research and clinical applications from these themes should seek to determine the positive behaviour change that was evident in the families that were interviewed, where the culmination of family interactions, expectations and concurrent partner weight loss indicates the potential longevity of weight management programs beyond patients' own participation.

Adult weight management patients' perceptions of family dynamics and weight status

Our overall objective was to describe the parent-child, romantic, and family dynamics of adult weight management program (WMP) patients, and associations with children's and partners' weight status. First, we determined if family functioning mediated the effect between parent-child feeding practices and perceived child weight status, and romantic relationship anxiety and avoidance and perceived partner weight status. Second, we assessed if perceived child and partner weight status moderated the associations between family functioning and parent-child feeding practices and romantic relationship anxiety and avoidance, respectively. Patients (N=203) who resided with a child and partner from two WMPs completed assessments of parent-child feeding practices (Child Feeding Questionnaire), romantic relationship anxiety and avoidance (Relationship Structures Questionnaire), family functioning (Family Assessment Device General Functioning Scale), and perceived child and partner weight status. Bivariate analyses determined differences in weight status and relationship dynamics and family functioning, and mediation and moderation analyses were conducted to answer the two research questions. Family functioning was not a mediator between romantic relationship dynamics and partner weight status or parent-child dynamics and child weight status. Lower family functioning was associated with higher parent-child restrictive feeding practices, only among children with overweight/obesity. Similarly, lower family functioning was associated with higher anxiety and avoidance in romantic relationships, only for partners with overweight/obesity. Patients with children and/or partners with overweight/obesity reported more impaired family dynamics and functioning, compared to patients with children and/or partners with a healthy weight status.

Rationale and design of a feasibility and acceptability RCT of romantic partner and support figure attendance during bariatric surgery visits

As US obesity rates increase, more patients, particularly females, are seeking out bariatric surgery. As bariatric surgery patients' social supports have been vastly understudied, clinicians and researchers have limited information about how to include support figures, including romantic partners, in the surgery process. To address this gap in knowledge, we are conducting a four-arm randomized controlled trial to assess the feasibility, acceptability and preliminary efficacy for the inclusion of romantic partners and support figures throughout the bariatric surgery process for a group of 110 women age 18 years or older. Patients will be randomized based upon their cohabitating romantic relationships at baseline. Female patients who have a cohabitating romantic partner will be randomized to one of two arms: partner attended (PA), and partner attended treatment as usual (PA-TU). To provide greater detail about social support during the bariatric process, interested patients (female or male) not in cohabitating romantic relationships will be randomized into support figure attended (SFA) and SFA-TU arms. Four data collection points are planned, including 4-months pre-surgery, 2 weeks pre-surgery, 2 weeks and 2-months post-surgery. Feasibility and acceptability of support figure/partner attendance collected at the final data point. Patients and support figures/partners will complete weight status, health behaviors, support for behavior change and relationship quality assessments at each time point. The rationale, design, theoretical framework, and methodology for the study are described. The results of this study will identify how support figures/partners influence patients’ health behavior change and weight loss, and how relationships change over the surgery process.
