Emotional well-being hit hardest in families managing Rett syndrome
Study: Brazilian respondents reported reduced overall quality of life
Written by |
Families of girls and young women with Rett syndrome reported reduced overall quality of life, with emotional well-being emerging as the most affected area, according to a study from Brazil.
Better family quality of life was associated with higher income, private health insurance, regular school attendance, and the absence of aggressive behaviors among girls with Rett. Physical functioning scores were particularly low.
“This study demonstrates that [family quality of life] among Brazilian families of girls with [Rett] is below the satisfaction threshold, with emotional well-being emerging as the most compromised domain,” researchers wrote.
The study, “Family quality of life in the context of Rett syndrome: insights from Brazilian families,” was published in the Journal of Community Genetics.
Rett places significant burden on patients and their families
Rett syndrome is chiefly caused by mutations in the MECP2 gene that result in reduced levels of functional MeCP2, a protein that regulates the activity of other genes and helps maintain the health of brain cells. This disrupts normal brain development and function, and leads to symptoms such as loss of motor skills, difficulty communicating, and cognitive and behavioral issues.
Because the MECP2 gene is on the X chromosome, Rett mainly affects females, who generally have two copies of this sex-determining X chromosome, meaning they can inherit one mutated copy and one healthy copy. Males have one X chromosome, so if the MECP2 gene is mutated, it cannot be compensated for by a healthy one, and they usually develop a much more severe clinical picture.
Considering its broad physical and cognitive impact, Rett places a significant burden on patients and their families.
In this study, researchers in Brazil evaluated family quality of life in 70 families of girls and young women with Rett syndrome and its association with the children’s sociodemographic and clinical characteristics. More than 90% of families had three or more people, and 58.6% of girls with Rett had at least one sibling.
Family quality of life was assessed using the Beach Center Family Quality of Life Scale (BCFQoLS) and Pediatric Quality of Life Inventory (PedsQL). BCFQoLS ranges from 1 (very dissatisfied) to 5 (very satisfied). PedsQL assesses quality of life in children, adolescents, and young adults, with scores ranging from 0 to 100 (higher scores indicate better quality of life).
[Family quality of life] refers to the collective well-being of all family members and the positive aspects of family life, particularly in the context of raising a child with a disability.
According to the investigators, family quality of life is assessed across domains such as family interaction, parenting, emotional well-being, physical and material well-being, and disability-related support.
“[Family quality of life] refers to the collective well-being of all family members and the positive aspects of family life, particularly in the context of raising a child with a disability,” they wrote. “Rather than focusing solely on the individual’s quality of life, [family quality of life] highlights the dynamic interaction between individual and family-level needs, and how environmental and relational factors contribute to overall family functioning.”
The mean family quality-of-life score was 3.68, which is below the defined satisfaction threshold of 4. The lowest BCFQoLS score was reported for emotional well-being (3.16). Conversely, the highest scores were in the family interaction domain (3.8), which particularly covers whether families enjoy spending time together and show that they love and care for each other, and disability-related support (3.81).
In PedsQL, the lowest score was for physical functioning (38.6), including participating in sports and other physical activities, lifting heavy objects, and taking a bath/shower independently. Higher scores were reported in emotional functioning (63.9), including worrying about what will happen, and feeling sad, afraid, or angry.
Better family quality of life was significantly associated with having a family income higher than four official Brazilian minimum wages (currently more than 6,484 Brazilian real, or about $1,289 U.S.), access to welfare benefits and private health insurance, higher parents’ educational levels, and parents working outside the home. Higher quality of life was also linked to the patients’ age, attending regular school, and showing no aggressiveness.
According to the researchers, effectively supporting these families requires a combination of emotional support for caregivers, socioeconomic assistance, inclusive education, and medical and psychological care for girls and young women with Rett.
“These approaches have direct implications for public policies and service provision in low- and middle-income countries,” they wrote.
