- Ingestão compulsiva na obesidade: O peso do comportamento e da satisfação com o suporte numa realidade insular e continentalPublication . Silva, Maria Rita Garoupa Albergaria; Pimenta, FilipaO crescente número de indivíduos com obesidade e ingestão compulsiva no panorama mundial constitui um problema de saúde pública. Torna-se relevante compreender as especificidades experienciadas por estes indivíduos. Objetiva-se investigar se a ingestão compulsiva em pessoas com obesidade é influenciada pelo comportamento alimentar, pela satisfação com o suporte social, pelo IMC, por variáveis sociodemográficas, de saúde e estilo de vida. Pretende-se, também, comparar a prática de ingestão compulsiva entre indivíduos de Portugal continental e da ilha de São Miguel, Açores – arquipélago com maior incidência nacional de obesidade. Esta amostra é constituída por participantes de Portugal continental e de São Miguel (n=187). Os resultados demonstraram associação entre a ingestão compulsiva e a ingestão externa (β=,559; p<,001) e entre a ingestão compulsiva e a ingestão emocional (β=,530; p<,001). E associação entre a ingestão compulsiva e a satisfação com o suporte amigos (β=-,206; p=,016). Não se verificou associação entre a ingestão compulsiva e o IMC (r=,225;p=,609), nem diferenças entre os participantes insulares e os de Portugal continental nesta ingestão (t(115,897)=-1,382;p=,170). Sugerem-se intervenções que promovam estratégias de coping adaptativas, relativamente à ingestão emocional e à externa e intervenções para facilitação de relacionamentos interpessoais através de atividades que fomentem práticas saudáveis (e.g., exercício físico) e redes de apoio. A ausência de diferenças entre a amostra insular e a continental relativamente à ingestão compulsiva coloca a hipótese de outras variáveis (e.g., gastronomia rica em sódio) explicarem as suas diferenças na prevalência de obesidade, que não as estudadas nesta investigação.
- "Menopause – Representantions, predictors and management of vasomotor symptoms, and impact on the couple’s sexual functions"Publication . Silva, Maria Rita Garoupa Albergaria; Pimenta, FilipaABSTRACT: The experience of menopause, despite being a natural physiological phenomenon and transversal to all women, can facilitate the emergence of vasomotor symptoms (VMS) and is influenced by representations, lifestyles, sociocultural context (among others) and, therefore, idiosyncratic for each woman. As such, the study of menopause representations proved to be relevant through: 1) development of an instrument guided by the Common-Sense Model of Self-Regulation (CSM-SR); 2) assessment of couples at middle-age, as well as the study of predictors of menopause symptoms’ (MS) perceived severity and the application of an intervention intended to modify these predictors and, thus, decrease their perceived severity. Four studies were carried out (3 transversal and descriptive-observational and 1 longitudinal and quasi-experimental) with Portuguese women aged between 45 and 65 years. The status, the representations and MS were variables common in all studies. The MenoSentations-Questionnaire, a culturally validated instrument, was developed to measure representations of menopause in 309 Portuguese women. It was based on the 5 cognitive components of the CSM-SR (identity, consequences, control, duration and cause), demonstrating adequate psychometric qualities. It proved to be useful both for the assessment of (mis)adjusted menopausal beliefs as well as for delineating cognitivebehavioural interventions (CBI) aiming to improve the menopause experience (Chapter 2). Knowing that genitourinary syndrome of menopause (GSM) and VMS (hot flushes and night sweats) are the most prevalent and problematic MS in middle-aged women’s daily life, and that the representations of menopause can determine the GSM’s management and, therefore, impact on women’s and the couple sexual functioning, the middle-aged couples were evaluated. We explored whether 28 Portuguese couples' representations of menopause influenced their sexual functioning, concluding that only men's negative representations impaired in their own sexual functioning (Chapter 3). Subsequently, a structural model was developed to understand the predictors of MS’ perceived severity in 505 Portuguese women (with special emphasis on potentially modifiable behaviours/aspects of diet and lifestyle). It was concluded that women with obesity, iatrogenic menopause, psychological problem, alternative complementary medicine’s users and frequent users of caffeinated beverages experience greater MS’ severity (Chapter 4). These results proved to be relevant to guide the intervention that followed, in the course of this doctoral thesis, for MS’ attenuation. Thus, in order to alleviate the problematic VMS’ experience in Portuguese women, MENOS2 (group CBI, effective in VMS’s reduction in English women) was adapted to the Portuguese language and culture (MENOS-PT), taking also in consideration the results obtained in Chapter 2 and 4. The MENOS-PT was applied and their effectiveness was tested in 8 Portuguese women, evaluating them in 4 times: T0–before MENOS-PT; T1– after the implementation of MENOS-PT; T2–3 months later; T3–6 months later. The results of this pilot study revealed the decrease of problematic VMS’ experience and frequency of hot flushes over time (T0-T3); the frequency of night sweats decreased only between T0- T2. Participants reported improvements in perception and perceived severity of MS, decreased perception of negative consequences (T0-T3) and greater perception of menopause’s control, awareness, and cause (T0-T2). Women showed improvements in quality of life only at T1, with no improvements in the perceived positive consequences of menopause, nor in the quality of sleep at any evaluation moment. This set of studies aimed to contribute to a better understanding of menopause based on a bio-psycho-socio-cultural perspective, namely in the measurement of menopause’s representations, its impact on sexual functioning, the determinants of exacerbation of MS’ severity, as well as on the CBI availability that demonstrated improvements in problematic menopause experiences.
