Background: Chronic diseases are one of the main causes of dependency and disability, which will cause the patient to require a caregiver at some point, consequently the prevalence of caregiver syndrome will increase. Caregiver syndrome is defined as the multidimensional response of negative appraisal and perceived stress as a result of caring for an individual with a medical condition.

Objective: To determine the factors associated with caregiver syndrome in patients with chronic kidney disease on peritoneal dialysis.

Methods: Cross-sectional analytical study. The variables collected were: sex, age, marital status, relationship, socioeconomic level, and hours of care per day, months of patient care, occupation, caregiver syndrome and anxiety. To know the caregiver syndrome, the questionnaire "Zarit Caregiver Scale" was applied. To establish symptoms of anxiety, the "Beck Anxiety Inventory" was used. In the bivariate analysis, odds ratio and Chi-Square with a confidence interval of 95% was implemented, a p <0.05 was considered significant.

Results: Of the 69 patients in the population, 44 suffered caregiver syndrome. The grade of caregiver syndrome was: intense overload 42% and light overload 21%. Caregiver profile: 49 (71%) women with a mean age of 44 years, married. 33 (47%) caregivers are sons/daughter of the patient, 34 (49%) were working, 44 (63%) were work active, 42 (60%) caregivers spent more than 10 hours with the patient, 28 (40%) had between 1 and 6 months in this activity. 42 (60%) presented symptoms of anxiety. A significant association (p<0.05) was found between caregiver syndrome and the variables marital status, socioeconomic level, kinship, occupation, anxiety and time in care.

Conclusions: The prevalence of caregiver syndrome is higher in the state of Sonora compared to the Northeast and Southeast of Mexico. The profile of the caregiver has not changed much despite the evolution over time, but the prevalence of caregiver syndrome is increasing.

Currently in Mexico, 47.8% of older adults have some type of disability and suffer the consequences of uncontrolled chronic diseases, eventually requiring more support from informal caregivers [1]. Terminal Chronic Kidney Disease is one of the main diseases that, due to its long evolution, cause total or partial dependence in the individuals who suffer from it, which leads to the need for an informal caregiver [2]. A caregiver is defined as any person who spends most of their time caring for the patient, covering their basic needs, who provides physical, emotional and sometimes economic support to any disabled or dependent patient; most informal caregivers are characterized by having an affective bond, with family members being the main caregivers and not receiving financial remuneration for their role as caregivers [3,4].

All people who perform a caregiver role without the proper knowledge, training and technique will suffer an overload or collapse in their health status. Secondary to all the adaptation changes, and in the performance of their role, caregivers tend to suffer a series of alterations in their biopsychosocial health status, and at a certain point in their lives they suffer a collapse or overload, which is defined as the multidimensional response of negative appreciation and perceived stress as a result of caring for an individual causing a set of physical, mental and socioeconomic problems in caregivers [5-6]. During the disease evolution process, the caregiver is completely unaware of the risk involved in playing this role for a prolonged and indefinite time. The risk factors that are recognized for overload are divided into 3 aspects; factors related to the person cared for, factors related to the caregiver and factors related to social support [7].

The diagnosis is usually based on an adequate clinical history, as well as on the application of the Zarit caregiver scale. The caregiver syndrome (CS) leads to a deterioration of the quality of life, the World Health Organization (WAO) defines it as "the perception that an individual has of his place in existence, in the context of the culture and the system of values in those he lives and in relation to his expectations, his rules and concerns” [7] having repercussions on his personal, family and social functionality. The present study aims to determine the factors associated with caregiver syndrome in patients with chronic kidney disease on peritoneal dialysis.

Material and Methods

Study Design and Population

An analytical cross-sectional study was carried out in Obregon City, Mexico, during March and August 2020, the research was carried out in the Family Medicine Unit #1 (FMU 01) of the Instituto Mexicano del Seguro Social (IMSS). 69 participants aged 20 to 70 years who were companions of patients with CKD during the outpatient consultation, who agreed to participate in the study through informed consent, were interviewed. A convenience sampling was performed, including all primary caregivers of patients with chronic kidney disease on peritoneal dialysis. Participants with a history of diagnosis of psychiatric illness and who shared patient care with another person were excluded from the study.


The collection of variables was done with a standardized data form. The variables collected were: sex, age, marital status, kinship, socioeconomic level, hours dedicated to care, time spent caring for the patient, occupation, caregiver syndrome and anxiety. The caregiver syndrome diagnosis was made with the Zarit scale, an instrument validated in several languages, including Spanish, with a Cronbach's alpha of 0.90. It consists of 22 items on a Likert-type scale with 5 response options; 0 = never, 1 = rarely, 2 = sometimes, 3 = often, and 4 = almost always. The total score ranges from 0-88 points, with the following cut-off points; less than 46 points there is no overload; 47-55 points, slight overload; more than 56 points, intense overload. The Beck Anxiety Inventory is an instrument that describes anxiety symptoms related to physical manifestations, validated with a Cronbach's alpha 0.83, it is composed of 21 items on a Likert-type scale, with the following cut-off points: 0-21 points, mild anxiety; 22- 35 points, moderate anxiety; and more than 36 points, severe anxiety.

Statistical analysis

Once the information was collected, the analysis was carried out using the SPSS version 25. Descriptive statistics were used, the qualitative variables were expressed as frequencies and percentages, and the quantitative variables as measures of central tendency and dispersion. In the inferential analysis, the non-parametric chi-square test was used for categorical variables and odds ratio for relative risk. The results were evaluated in a confidence interval of 95%, a value of p <0.05 was considered as significant.


The study was approved by the Local Committee for Ethics and Health Research number 204, with registration number R-2021- 2603-042. The research was conducted under the General Health Law on Health Research, the Declaration of Helsinki and bioethical principles.


69 surveys were applied to caregivers of patients with chronic kidney disease on peritoneal dialysis. The age distribution was from 20 to 60 years old with an average of 44.01 ± 11.27. Regarding gender, 71% (n= 49) were female; 71% (n= 49) were married. The most frequent socioeconomic level (49%) was working class. According to kinship; 47% (n= 33) were sons/daughter who were responsible for the care of the patient; 60% (n= 42) of the caregivers had more than 10 hours of care per day, with a median of 4. In relation to the time spent as a caregiver; 40% (n= 28) were between 1 and 6 months old. In the occupation, 63% were active workers. Of the total number of caregivers with anxiety, 34% (n= 24) presented mild symptoms, 13% (n= 9) moderate symptoms, and 13% (n= 9) severe symptoms. According to the overload classification: 21% (n= 15) had mild overload and 42% (n= 29) intense overload.
