Introduction

The body image is the multidimensional construction of the internal and external representations of the corporal structures added to the physical appearance, and may be influenced by sex, age, means of communication, in addition to beliefs and values inserted in a culture¹. Such values can change throughout life due to the fact that it is a subjective mechanism in which the mental representation of physical appearance depends on the way the individual conceptualizes his/her own body².

Therefore, the search for the ideal body shape based on unattainable models or references, which are far from the reality of most of the population, has as consequence the increasing dissatisfaction of people with their own appearance^{3), (4}. Considering this theme there is a vast amount of research based on the search for an ideal body image that assess the levels of satisfaction or dissatisfaction of some individuals with their body⁵, and comparisons between the self esteem and body image satisfaction of people who practice physical activities⁶.

In this sense, this topic also can be evaluation in elderly body image, showing that practice physical exercise, which shows that the practice of physical activities favors the experience with the body by promoting a positive and integrative body image⁷. Beyond to a better perception of body image, the practice of physical exercise in the elderly seems to be a factor that allows greater satisfaction with life and self-esteem during aging^{6), (8}.

According to Matos⁹, such an appreciation of body image has increasingly taken the elderly to fitness centers, as well as to gyms for senior citizens, aesthetic centers, nutritional or pharmaceutical support and even to plastic surgeries in order to improve body dimensions. In this sense, most studies show fragmented analyzes on the level of physical activity, satisfaction or dissatisfaction of body image and other factors related to the theme, but less is discussed about the influence of weight training in elderly body image.

Therefore, this study aims at identifying the factors associated with the dissatisfaction with the body image of the elderly who practice weight training.

Method

This is a quantitative observational cross-sectional study.

Sample

The sample, chosen by convenience and intentionally, embraced 174 male and female elderly subjects (65.06 ± 4.98 years) who practiced weight training at one of the fitness centers in Maringá city, state of Paraná. These centers¹⁵ were chosen for data collecting for offering such a modality, and they were randomly drawn according to the list of those accredited in the Regional Council of Physical Education of Paraná.

The elderly were properly enrolled in the weight training modality in one of such fitness centers. The individuals with neurological and cognitive deficits, which were perceptible to the researchers and that prevented the elderly from answering the questionnaires, were excluded. Those who agreed to participate in the research signed the Free Informed Consent Form (FICF). They were interviewed in the fitness centers, after their authorization.

The study was approved by the Standing Committee on Ethical Research with Humans under the opinion n° 1.694.517/2016.

Tools

A semi-structured questionnaire was used to characterize the sociodemographic, health, and weight training profiles of the sample, which consisted of questions related to the age group (60 - 70 years old, 71 - 80 years old); sex (female, male); marital status (with a partner, without a partner); monthly income in minimum wage (MW) related to the amount in force in 2016 (up to 1 MW; 1.1 to 2 MW; over 2 MW); education (illiteracy, incomplete elementary education, complete elementary education, complete high school, complete higher education); smoking (has never smoked, has already smoked, currently smokes); race (Caucasian, black, Asian); being retired (yes, no); occupational situation (active, non-active); being a current student (yes, no); health self-perception (bad, regular, good, very good, excellent), body self-perception (slim; normal; fat); weight training time (less than 6 months, 6 months to 2 years, more than 2 years); weekly frequency of weight training (2, 3, 4, 5 or more times); reason for weight training practice (medical recommendation, leisure, aesthetic); body image dissatisfaction; being practicing another exercise (yes, no).

Body dissatisfaction was assessed by using the BSQ questionnaire, which consists of 34 questions and is self-filling - a 6-point Likert scale (1: never to 6: always). After summing the points of the questions, the classification of body dissatisfaction levels was carried out: absence of body dissatisfaction - under 80 points; a slight dissatisfaction - from 80 to 110 points; a moderate dissatisfaction - from 110 to 140 points; a severe body dissatisfaction - score equal to or above 140 points. The evaluation was performed by considering the corporal form and concern expressed during the last four weeks of the date of collection¹⁰.

Procedures

Initially, the Regional Council of Physical Education (CREF/PR) was contacted in order to obtain the list of fitness centers that offered weight training, located in Maringá city, state of Paraná. Subsequently, 15 fitness centers were drawn. After the authorization of those responsible for the centers, data collection was started, before or after the practice of weight training. The elderly who accepted to participate in the research signed the Free Informed Consent Form. Data collection was carried out from May to July, 2016.

Statistical analysis

Data analysis was carried out by using the SPSS 22.0 Software, in addition to a descriptive and inferential statistics approach. In the descriptive approach, the absolute and relative frequencies were distributed to the categorical variables (sociodemographic, health and physical activity). The numerical variables were expressed through the mean and standard deviation. In inferential statistics, the Chi-squared test and, when necessary, Fisher's exact test, were used to investigate the proportional differences considering the prevalence of body dissatisfaction based on sociodemographic, health, and physical activity variables. The Binary Logistic Regression (gross and adjusted analysis) was used to evaluate the associations of sociodemographic, health and physical activity variables (independent variables) with the presence of body dissatisfaction (dependent variable) of the elderly. For both Chi-squared and Logistic Regression, the BSQ was reorganized into two categories: absence of dissatisfaction - those classified as free from body dissatisfaction; and presence of dissatisfaction - those who were classified as having some level of body dissatisfaction (slight, moderate or severe). For modeling the regression analysis only those variables that showed a level of significance equal to or less than 0.20, considering the association with the presence of body dissatisfaction in the chi-squared test, were considered. The model fit was verified through the Hosmer-Lemeshow test. The analyzes were performed by using the SPSS software version 20.0 (p < 0.05).

Results

Out of the 174 elderly subjects evaluated, 104 were female (59.8%) and 70 were male (40.2%). The majority were 60-70 years old (83.9%); they had finished high school (58%), had a partner (55.7%), had an income above 2 minimum wages (55.1%); they were Caucasian (78.7%), and they were not retired (73.6%), but with an inactive occupational situation (61.5%).

When the analysis was adjusted for all the variables, a significant association between the presence of body image dissatisfaction with age and sex (p < 0.05) was seen. It is highlighted that older people and women showed 1,110 (95% CI = 1,003 to ,251) and 3,120 (95% CI = 1,019 - 9,554) times more likely to be dissatisfied with body image when compared to younger subjects and men.

Discussion

The present study aimed at identifying the factors associated with the dissatisfaction with the body image of the elderly who practice weight training, a subject that, although strongly discussed in what refers to how much such dissatisfaction is seen in different contexts¹¹, it still lacks evidence in the literature regarding the profile of the elderly practitioners who practice weight training. In this sense, the results showed that there is a higher proportion of elderly with absence of body dissatisfaction, most of them are not retired neither been currently studying, and independent the time they practice weight training, the simple act of practice contribute to better perception of body image. Yet, it was found that be women and the older you get, can be an indicative to contribute to the body image dissatisfaction.

With aging, the physical changes that occur in the body are rejected by the elderly due to the image they have of themselves, which can make them develop a feeling of low self-esteem and self-devaluation¹². For this, practice exercise is important for this population, because for elderly, stay with high self-esteem, can contribute for better self-perception, and purpose of life^{8), (13}.

The majority of weight training practitioners of this study were female. Cardoso et al.¹⁴ also found that older women are more physically active and practice physical activity. The study by Krug et al.¹⁵ also showed that most of the elderly who practice different modalities of physical activity were female. This can be an indicative that it is necessary motivate male elderly to practice more exercise and/or be more careful with their health.

Another important result was that even in elderly people, be women is a factor that may favor greater body image dissatisfaction. This is found in Weinberger et al.¹¹ meta-analysis and in Almeida and Baptista³, who verified that BI dissatisfaction is more evident in women. Comparing with this, the present investigation can contribute for interventions with elderly women, comprehending that even older women can be perfectionist with their body and collaborate with this self-perception.

The studies by Mazo et al.¹⁶ and Meurer et al.¹⁷, carried out with elderly women who regularly participate in regular physical exercise programs. These studies showed a high self-esteem and self-image in the active elderly, and verified that the participation in regular physical activity programs significantly contributes to the improvement of self-esteem and self-image of the elderly, who consequently have a better body satisfaction. Studies with old women report that a reduced number of diseases and the practice of physical activities have a positive effect on satisfaction with self-esteem and body image¹⁸.

Coradini et al.¹⁹ analyzed the body image satisfaction of active elderly women, and then related the physical exercise with body image, thus finding that most of the elderly women were dissatisfied with their body image, but they recognized the benefits provided by physical exercise. Pereira et al.²⁰ related the anthropometric indicators with the body image perception of elderly women, pointing out that the majority of them were dissatisfied for being overweight. Such results were also found by Chaim, Izzo & Sera¹², and Londoño and Velasco²¹ who showed that the body image dissatisfaction may negatively influence the quality of life.

However, Conterato and Daronco²² have identified positive changes in the body image perception of elderly women after starting weight training, which reinforces the benefits of the modality for a better self-image. This can be an indicative of the importance of physical exercise during aging, in be a factor for greater self-evaluation and wellbeing. For this, it is important to know why and which kind of exercise elderly looking for.

The study by Zawadski and Vagetti²³, which aimed to know the main reasons that lead the elderly to practice weight training, showed health maintenance and the prevention of diseases as the first reasons. Yet, it is the medical indication, making friends, the improvement of life quality, and increased self-esteem. The present study, the elderly who practice weight training and had no body dissatisfaction go to fitness centers due to medical recommendation and leisure. These indicate that, even though the elderly seek the physical exercise by medical indication, for this population, it is extremely important the social contact that the activity provides

The present study shows that the majority (16.7%) of the elderly dissatisfied with the body image earn more than two minimum wages. A study carried out with elderly women living in low-income communities in the northeastern region of Brazil showed that body dissatisfaction is the main factor associated with insufficient physical activity, even when controlled by sociodemographic factors and other characteristics related to health status²⁴.

The study by Coelho and Fagundes²⁵ reports that the higher the purchasing power, the better the relationship with body image, which reflects the variation in body image satisfaction among different social classes that influence the perception of body image. However, the beauty standard imposed by society affects individuals regardless of the social class^{2), (26}.

In the present study 69% of the elderly have been practicing weight training for 6 months to more than two years. The regular practice of physical activities, besides preventing addictions, is a stimulus to well-being, contributing to an improvement in independence and health self-perception, which reflects in a better self-esteem and life satisfaction^{8), (27}, consequently, a better satisfaction with body image²⁸.

The improvement of mental and physical health, social life, socialization and friendship are the main reasons that make the elderly begin and remain in physical activity programs^{(16, 20)}. The participation of the elderly in physical exercise programs, such as weight training, may be a practice that contributes more than physical fitness²⁹, but can support the quality of life, self-esteem and body satisfaction of the elderly, although there are other aspects that contribute to increase these variables^{27), (30}.

As limitations of this study, the absence of a group of elderly people who do not practice physical exercise is highlighted, as well as elderly people who practice other types of exercise, in order to compare the data. The way of drawing the places of research may also be indicated as a limitation. A research on this same subject with older adults (80 years old and more) should be carried out, as well as a follow-up of this population in longitudinal studies in order to understand the behavior of body dissatisfaction with the aging process.

Conclusion

Based on the results obtained, it can be concluded that the sociodemographic factors can be considered as intervenient ones for body dissatisfaction of the elderly who practice weight training. It is emphasized that, as aging comes, the elderly become increasingly dissatisfied with their own body, and this situation is more evident in women. As practical implications of these findings, it can be pointed out the need of family members and health professionals to be aware of such indicatives in the elderly. In addition, the relevance of regular practice of exercises to reduce this body dissatisfaction is highlighted.
