Purpose

This research identified whether adolescent religiosity was associated with body satisfaction and disordered eating in adolescence and early adulthood and explored gender/sex differences in these associations.

Methods

Project EAT (Eating and Activity in Teens and Young Adults) is a longitudinal cohort study following participants from adolescence into young adulthood. For this analysis (N = 1620), religiosity (importance of religion and frequency of religious service participation) during adolescence was examined as a correlate of body satisfaction and disordered eating (binge eating, maladaptive behaviors intended to lose or maintain weight, eating to cope, and dieting) at the same life stage (EAT-II, 2003–2004, Mage = 19.4 years) and during young adulthood (EAT-IV, 2015–2016, Mage = 31.5 years). Analyses used linear and logistic regression models adjusted for demographics and adolescent body mass index.

Results

During adolescence, females who placed greater importance on religion had higher body satisfaction, 22% higher odds of binge eating, and 19% greater odds of dieting in the past year, while more frequent attendance of religious services was associated with higher body satisfaction and 37% greater odds of dieting past year. Among males, only frequent attendance of religious services was associated with higher adolescent body satisfaction. Longitudinally, among females, only frequent attendance of religious services in adolescence predicted higher levels of body satisfaction in young adulthood. No significant longitudinal associations were observed among males.

Conclusions

Our findings contribute to understanding the complex interplay between religiosity, gender, and body satisfaction. Further research should explore cultural factors influencing these associations and qualitative aspects of religious experiences to inform nuanced interventions.

Level of evidence: Level III, cohort study.

Religion plays an important role in the lives of many individuals around the world [1, 2]. Religiosity encompasses individuals’ engagement in religious rituals and practices associated with a higher power or a specific faith [3]. Research suggests religion and spirituality can positively influence overall health and well-being by encouraging the adoption of a range of health-promoting religious practices [4, 5]. For instance, meditation and prayer are known to reduce stress and improve mental health, while active participation in community life strengthens social networks and support systems [4]. Moreover, religious teachings often emphasize values and a sense of purpose, advocate for a balanced lifestyle, and promote moderation and healthy living habits [4]. Many religions consider the human body sacred and impose specific restrictions on unhealthy behaviors such as overeating, smoking, and excessive alcohol consumption, deeming them both physically and spiritually harmful [4]. These perspectives highlight the interplay between physical, mental, and spiritual well-being. Previous research has examined the influence of religiosity on various health dimensions. Studies showed associations between religiosity and dietary behaviors [6–8], weight status [6, 9–12], mental health [5, 13], overall health promotion [9, 14, 15], and disease prevention [14, 15].

Numerous studies have investigated the relationship between religiosity and various aspects of body satisfaction and disordered eating, yielding a range of results. For example, a systematic review of 22 studies examining the relationship between religiosity/spirituality and disordered eating yielded mixed associations: six studies reported positive effects, four found negative effects, two showed mixed results, and three found no significant associations. In contrast, among 15 studies that examined religiosity/spirituality and body image, 12 noted positive associations [16]. The existing literature also showed inconsistent gender differences in these associations. For example, a cross-sectional study (68% women) found that body satisfaction in older men was positively associated with religious and existential well-being, whereas in older women, it was only linked to existential well-being [17]. Another cross-sectional study (72% women) showed that religious men had higher levels of purging, restricting, muscle-building behaviors, and negative attitudes towards higher weight status than religious women [18]. However, both religious women and men displayed similar levels of body dissatisfaction and binge eating. Conversely, two Canadian studies concurrently found no significant link between religiosity and body satisfaction or bulimia among Canadian women with ethnically diverse backgrounds [19, 20]. These studies, most of which were cross-sectional, have often relied on predominantly female adult samples and yielded inconsistent results [16–21], highlighting the need for further research to explore potential gender differences and the varying influence of religiosity on body image and disordered eating behaviors.

Building on these studies, the current study expands the extant literature to learn more about how religiosity may be related to body satisfaction and disordered eating among both females and males. The purpose of this present study is to explore in a population-based sample: (1) associations between religiosity in adolescence and body satisfaction and disordered eating (binge eating, eating to cope, maladaptive behaviors intended to lose or maintain weight, dieting) in both adolescence and young adulthood and (2) gender/sex differences in these associations. A hypothesis has not been made due to the inconsistencies in the literature to date. Findings will help public health professionals and researchers to understand the nuanced relationship between religious beliefs/practices, body image, and disordered eating across genders over time, providing important insights for creating targeted health interventions.

Methods

Study design and sample

This study used data from the Project EAT (Eating and Activity in Teens and Young Adults) study. Project EAT is a 15-year longitudinal, population-based cohort study focusing on behavioral, psychological, and socioenvironmental factors influencing dietary intake, physical activity, and weight-related outcomes in adolescents and young adults [22–25]. The data presented in this manuscript are derived from the follow-up surveys conducted in two waves: the earlier follow-up in 2003–2004 (EAT-II) and the latest follow-up in 2015–2016 (EAT-IV). During the 2003–2004 follow-up, we identified the contact details for 3,672 participants out of the original cohort of 4,746 (EAT-I, 1998–1999), receiving 2,516 completed surveys as a result of a mailing campaign (mean age = 19.4 ± 1.7 years), representing a 68.4% response rate. For the 2015–2016 follow-up, the survey was sent out to those original 1998–1999 participants who had completed at least one prior follow-up survey. From the available contact information for 2,770 individuals, we gathered data online, by mail, or by phone, achieving a 66.1% response rate and obtaining completed surveys from 1,830 young adults with an average age of 31.0 years (SD = 1.6). Overall, more than 88% of the individuals in the EAT-IV cohort had also completed the 2003–2004 mailed survey (n = 1,620), which constitutes the analytical sample for the present study. Study protocols were approved by the University of Minnesota Institutional Review Board. In 1998–1999, participants provided their written assent. For follow-up surveys, each participant received a consent form either included with mailed surveys or presented at the start of the online survey. By completing and returning the survey, participants implicitly indicated their consent to participate in the study.

Survey development

Key items from earlier study waves (Projects EAT-I, II, and III) were retained in the Project EAT-IV survey to facilitate longitudinal assessments and explore secular trends. The scale's psychometric properties were assessed using the entire EAT-IV sample. The item test–retest reliability estimates were utilized from a subgroup of 103 respondents who completed the survey twice in a time frame of 1–4 weeks [22]. In this study, two religiosity questions (importance of religion and frequency of religious service participation) were used as the primary predictors, which were only collected during the Project EAT-II (2003–2004) wave. Prior to being included in the Project EAT-II survey, the research team pretested the questions about the frequency of religious service attendance and the significance of religion with 20 young adults in focus groups. Young people who participated in pretesting completed a prefinal version of the survey on their own, and then they discussed the survey’s content, question phrasing, and response possibilities as a group.

Religiosity

Adolescent religiosity was examined by two separate questions (developed for the Project EAT study) regarding attitudes towards religion and religious practices: (1) how important is religion to you? with a four-point scale ranging from ‘not at all = 1’ to ‘very = 4’ and (2) how often do you attend religious services? with response options ‘never = 1,’ ‘rarely = 2,’ ‘once or twice a month = 3,’ and ‘about once a week or more = 4.’ Based on the median value of response options, the importance of religion (median = 3) was dichotomized as greater importance (very and moderately) and less importance (somewhat and not at all), while the frequency of religious service participation (median = 2) was dichotomized as more frequent participation (once or twice a month, and about once a week or more) and less frequent participation (never and rarely). Dichotomized versions of religiosity variables were used in the demographic characteristics of the participants to outline the sample. Meanwhile, continuous religiosity variables were employed in the regression models to explore the association between religiosity, body satisfaction, and disordered eating among both females and males.

Body satisfaction

In a modified version of the Body Shape Satisfaction Scale [26], participants reported their satisfaction (in both adolescence and young adulthood) with 13 different body parts (height, weight, body shape, waist, hips, thighs, stomach, face, body build, shoulders, muscles, chest, and overall body fat) on a 5-point scale ranging from ‘very dissatisfied’ to ‘very satisfied’ (α = 0.94; test–retest reliability = 0.82).

Disordered eating behaviors

Binge eating

Two questions assessed binge eating during adolescence and young adulthood (sources of the questions: [27–29]): “In the past year, have you ever eaten so much food in a short period of time that you would be embarrassed if others saw you (binge eating)?” and “During the times (past year) when you ate this way, did you feel you couldn’t stop eating or control what or how much you were eating?” with ‘yes’ and ‘no’ response options. Participants were classified as ‘yes’ if they reported any binge eating and ‘no’ if they reported no binge eating behaviors (test–retest agreement = 90%).

Eating as a coping strategy

To examine eating as a coping strategy in young adulthood, participants were asked to complete a 5-item Coping Subscale of the Motivations to Eat Measure [30] with response options ‘almost never or never,’ ‘rarely,’ ‘sometimes,’ ‘often,’ and ‘almost always or always’ (α = 0.92; test–retest reliability = 0.76). The 5-item in the Coping Subscale of the Motivations to Eat Measure includes eating due to feeling depressed or sad, worthless or inadequate, as a way to cope, receive comfort, and for distraction. In adolescence, eating as a coping strategy was not examined.

Maladaptive behaviors intended to lose or maintain weight

Maladaptive behaviors intended to lose or maintain weight during adolescence and young adulthood were examined by asking participants, “Have you done any of the following things in order to lose weight or keep from gaining weight during the past year?: engaged in fasting, ate very little food, used diuretics, laxatives, or a food substitute (e.g., powder or special drink), skipped meals, smoked more cigarettes, took diet pills, or induced vomiting.” Response options included ‘yes’ and ‘no’ [31, 32]. Participants were classified as engaging in maladaptive behaviors intended to lose or maintain weight if they endorsed one or more maladaptive behaviors intended to lose or maintain weight (test–retest agreement = 86%) [22].

Dieting

During adolescence, participants were asked, “How often have you gone on a diet during the last year?” with response options ‘never,’ ‘1–4 times,’ ‘5–10 times,’ ‘more than 10 times,’ and ‘I am always dieting.’ Response options were dichotomized as no (never) and yes (other responses) (test–retest agreement = 89%) [33, 34]. In young adulthood (EAT-IV), participants were asked, “Have you gone on a diet to lose weight during the last year?” with response options ‘yes’ and ‘no’ (test–retest agreement = 92%).

Demographic characteristics

Participants’ age, sex, ethnicity/race, body weight, and height were measured via self-reports on the survey during adolescence. Socioeconomic status (SES) at EAT-I [1(lowest)—5 (highest)] was derived based on parental education level, parental job status, public assistance eligibility, and access to free or reduced-cost meals at schools, consistent with other EAT studies [35, 36]. Participants’ body mass index (BMI) was calculated using weight (kg) divided by height squared (m2).

The religions in which participants were raised were examined by one question adapted from College Alcohol Study [37, 38], “In what religion were you raised?” with response options ‘none,’ ‘Buddhism,’ ‘Catholicism,’ ‘Islam,’ ‘Judaism,’ ‘Protestantism,’ ‘Shamanism,’ and ‘other.’

Statistical analysis

The descriptive statistics used dichotomized versions of religiosity variables (importance of religion and frequency of religious service participation). Chi-square, Fisher exact tests, and t tests were used to assess the associations between demographics and religiosity.

To examine the cross-sectional associations between religiosity and body satisfaction and disordered eating in adolescence, gender-stratified adjusted linear and logistic regression models were used. Models adjusted for age, race/ethnicity, SES, and BMI during adolescence.

Gender-stratified adjusted logistic regressions and linear regressions were also used to assess whether religiosity in adolescence longitudinally predicted body satisfaction and disordered eating in young adulthood. Models adjusted for race/ethnicity, SES, and BMI in adolescence and age in young adulthood.

All analyses were performed in R (version 4.3.1; R Development Core Team, Vienna, Austria). Statistical significance was set at p < 0.05. Data were weighted using the inverse of the estimated probability of a participant responding at both the 2003–2004 and the 2015–2016 because the attrition did not occur randomly from EAT-I [39]. This approach allowed for the weighted sample to reflect the demographic composition of the original school-based cohort more accurately, thus enhancing the ability to extrapolate the findings to the broader population of adolescents residing in the Minneapolis–St. Paul metropolitan area during the 1998–1999 period.

Results

Sociodemographic characteristics of adolescents by religiosity

During adolescence, participants were equally divided on gender/sex and identified as having been raised in a variety of religious traditions (see Table 1). Adolescents’ age, gender/sex, race/ethnicity, religion, and frequency of religious service participation differed by religious importance. More males (53.4%) reported greater religious importance compared to females (46.6%; p = 0.01). Religious service attendance was associated with age, race/ethnicity, socioeconomic status, religion, and religious importance (Table 1).Table 1 Sociodemographic characteristics of participants by religiosity (importance of religion and frequency of religious service participation) in adolescence (N = 1620)

Cross-sectional associations between religiosity and body satisfaction and disordered eating during adolescence by gender/sex

Among females, religiosity was cross-sectionally associated with body satisfaction and two disordered eating in adolescence in analyses adjusted for adolescent age, SES, race/ethnicity, and BMI (Table 2). Specifically, higher importance of religion during adolescence was associated with higher body satisfaction (β: 0.70; 95% CI 0.18, 1.21); 22% higher odds of past-year binge eating (95% CI 1.02, 1.47); and 19% greater odds of past-year dieting (95% CI 1.04, 1.37). On the other hand, more frequent religious service attendance was associated with higher body satisfaction (β: 0.67; 95% CI 0.12, 1.22) and 37% greater odds of past-year dieting (95% CI 1.18, 1.59). Among males, the only significant cross-sectional association found among males was that a higher frequency of religious service attendance was associated with greater body satisfaction in adolescence (β: 0.77; 95% CI 0.14, 1.40) after adjusting analysis for adolescent age, SES, race/ethnicity, and BMI (Table 2).Table 2 Adjusted cross-sectional associations between religiosity and body satisfaction and past year disordered eating in adolescence among females and males

Longitudinal associations between religiosity in adolescence and body satisfaction and disordered eating in young adulthood by gender/sex

In unadjusted models, our analysis showed no significant associations between the levels of religiosity in adolescence and body satisfaction or the prevalence of disordered eating in young adulthood when examining females and males separately (Data not shown).

Among female participants, in analyses adjusted for age in young adulthood and socioeconomic status, race/ethnicity, SES, and BMI at adolescence, more frequent religious service participation in adolescence was associated with higher body satisfaction (β: 0.67; 95% CI 0.11, 1.23) in young adulthood (Table 3). However, there was no significant association between religiosity in adolescence and any disordered eating in young adulthood among females. Among male participants, there were no associations between religiosity in adolescence and body satisfaction and disordered eating in young adulthood (Table 3).Table 3 Adjusted longitudinal associations of religiosity at adolescence with body satisfaction and past year disordered eating in young adulthood among females and males

Discussion

The current study assessed cross-sectional and longitudinal associations between religiosity in adolescence and body satisfaction and disordered eating behavior outcomes in both adolescence and young adulthood among a diverse, population-based sample. In adjusted cross-sectional models, we found female adolescents who placed higher importance on religion and attended religious services more frequently reported higher body satisfaction and were more likely to binge eat or diet, while those attending religious services more frequently were also more likely to diet. Among male adolescents, frequent religious service attendance was associated with higher adolescent body satisfaction. In adjusted longitudinal models, we found more frequent religious service participation during adolescence predicted higher body satisfaction a decade later among females but not disordered eating. Conversely, adolescent religiosity did not significantly predict body satisfaction or disordered eating in young adulthood among males. Overall, some of the findings were not consistent across analyses nor in consistent directions (e.g., higher body satisfaction but higher levels of dieting).

The cross-sectional finding indicates that higher religiosity (characterized by placing higher importance on religion and more frequent religious service attendance) was associated with greater body satisfaction in adolescence among females. These positive associations between religiosity and body satisfaction align with the work of Kim [40], who showed that women who spent more time in religious activities had greater body satisfaction [40]. Similarly, Homan and Cavanaugh (2013) found that a strong, warm, and secure connection with one’s God was associated with higher body appreciation among young women in their cross-sectional analysis [41]. While these findings underscore the potential benefits of religious and spiritual community support systems for women’s body image and well-being, it is essential to interpret them with caution because we did not see associations with most of the outcomes, and the direction of the findings varied across different analyses. Nonetheless, these insights suggest the potential value of fostering supportive environments within religious communities that prioritize overall well-being and acceptance. Identifying and addressing any underlying societal ideologies or cultural pressures that may inadvertently contribute to body dissatisfaction is crucial in creating nurturing spaces where women feel empowered to embrace their bodies.

The present study showed that higher religiosity was associated with higher body satisfaction and higher odds of dieting among females during adolescence. This dual-faceted influence of religiosity on body satisfaction and dieting may have also been influenced by other variables, such as cultural, familial, or societal attitudes [42, 43], which could interplay with individual religious beliefs in complex ways. For example, many religions advise modesty in dress [44], which can influence body satisfaction positively by reducing exposure to idealized body types. However, societal factors such as media exposure emphasizing thinness or familial practice of frequent discussions on appearance, thinness, eating, and/or weight could lead to dieting and increase pressure to conform to specific body standards [45–47]. Thus, these findings call for a deeper exploration into the other factors and types of religious messages about the body in different religions practiced during adolescence and how they may shape long-term attitudes and behaviors related to body image and eating behaviors.

For males and females, cross-sectional analyses indicated a positive association between religious service attendance and body satisfaction. This cross-sectional association persists into young adulthood among females but not among males. The initial association might reflect greater stability in the family or a sense of belonging to religious community life during adolescence [43, 48], which could contribute to better body satisfaction. Yet, in adulthood, other factors likely become more influential for male body image [49], potentially overshadowing the early influence of religious community engagement. Specific factors such as evolving social norms, individual identity development, and changing perceptions of masculinity may shape whether religiosity positively or negatively influences body image. Further investigation into these nuanced dynamics is essential for a comprehensive understanding of the interplay between religiosity and body image across the lifespan.

It is important to interpret our findings in light of the study’s limitations. Our survey assessed religiosity only at one point in time and utilized only three questions. Future research would benefit from a more detailed evaluation of religiosity, including assessing religiosity over time. We also had limited power to detect differences across religions. While our study focused on adolescents’ religiosity, it is essential to recognize that their attendance at religious services may be shaped by parental factors, such as upbringing, family values, and parental encouragement. In addition, being involved in religious activities can contribute to body satisfaction because young people may feel a sense of community and belonging not related to the religious aspects of their experiences. Moreover, the importance of religion and the frequency of religious service attendance questions were not from a validated scale. The current study also has important strengths. First, the study’s large ethnically and socioeconomically diverse sample enhances the ability to generalize results to broader groups of adolescents and young adults. In addition, the longitudinal study design allowed examination of the predictive nature of religiosity, with our follow-up period notably longer than that of prior studies to the best of our knowledge.

Our findings highlight the complex relationship between personal faith practices in youth and perceptions of body satisfaction in adolescence and young adulthood. Although adolescent religious service attendance may positively influence body satisfaction during young adulthood for some females, this association was not found among males. Therefore, these gender/sex differences show that public health initiatives within religious settings should be approached carefully and thoughtfully, with an emphasis on promoting a healthy body image. It is important to explore whether training for clergy, youth directors, or the wider public would be valuable, taking care to avoid any unintended negative consequences. Further research is vital to deepening an understanding of cultural norms, traditions, values, and practices within different religious groups, as well as the qualitative aspects of religious experiences to provide deeper insights into the inconsistencies observed in quantitative analyses as well as to enhance the effectiveness of interventions targeting diverse faith communities. This considered approach should prioritize cultural sensitivity and avoid any potential harm in its application.

What is already known on this subject?

Religiosity plays a significant role in many people’s lives, influencing their beliefs, behaviors, and overall well-being. In many religions, the body is considered sacred, and certain behaviors that are harmful, both physically and spiritually, are discouraged. However, existing research, often based on cross-sectional studies, presents mixed findings regarding the influence of religiosity on body satisfaction and disordered eating in both females and males.

What this study adds?

This study advances our understanding of how religiosity in adolescence relates to body satisfaction in adolescence and young adulthood, especially among females. These findings have the potential to benefit public health professionals and researchers by contributing to the development of targeted interventions focused on promoting body satisfaction within religious communities.
