ABSTRACT

Introduction:

in previous studies, obesity was identified as a risk factor for inflammatory breast disease, but its causality is uncertain. In thepresent study, we performed a two-sample Mendelian randomization (TSMR) analysis to investigate the causal relationship between obesity andinflammatory breast disease.

Methods:

we use body mass index (BMI) as a measure of obesity. Data for single nucleotide polymorphisms (SNPs) associated with BMI wereobtained from UK Biobank. Data for single nucleotide polymorphisms (SNPs) associated with mastitis were obtained from FinnGen Biobank. We usedseveral MR analysis methods, such as inverse-variance weighting (IVW), MR-Egger, weighted median, simple mode and weighted mode to makeour results more convincing. We also performed MR-PRESSO test, MR-Egger test, heterogeneity test, pleiotropy test and leave-one-out analysisto make our analysis results more robust and credible. We used odds ratio (OR) to evaluate the causal relationship between BMI and mastitis.

Results:

based on the IVW random effects model, we found that a one-standard deviation (SD) increase in BMI increased the risk of mastitis by62.1 % (OR = 1.621, 95 % CI 1.262-2.083, p = 1.59E-4), which is almost consistent with the results of several other methods.

Conclusions:

in European individuals, an increase in the number of BMI increases the risk of inflammatory breast disease. People with high BMIneed to control their weight to reduce the incidence of inflammatory breast disease.(AU)
RESUMEN

Introducción:

en estudios previos, la obesidad se identificó como un factor de riesgo para la enfermedad inflamatoria de mama, pero su cau-salidad es incierta. En el presente estudio, se realizó un análisis de aleatorización mendeliana de dos muestras (TSMR) para investigar la relacióncausal entre la obesidad y la enfermedad inflamatoria de mama.

Métodos:

se empleó el índice de masa corporal (IMC) como medida de obesidad. Los datos de los polimorfismos de nucleótido único (SNP)asociados con el IMC se obtuvieron del Biobank de Reino Unido y los datos de los polimorfismos de nucleótido único (SNP) asociados con lamastitis se obtuvieron de FinnGen Biobank. Se utilizaron varios métodos de análisis de RM, como la ponderación inversa de la varianza (IVW),RM-Egger, mediana ponderada, modo simple y modo ponderado para que nuestros resultados fueran más convincentes. También se realizaronla prueba MR-PRESSO, la prueba MR-Egger, la prueba de heterogeneidad, el test de pleiotropía y la validación dejando uno fuera (en inglés,leave-one-out) para que los resultados de nuestro análisis fueran más sólidos y creíbles. Se utilizó la odds ratio (OR) para evaluar la relacióncausal entre el IMC y la mastitis.

Resultados:

basándonos en el modelo de efectos aleatorios IVW, se halló que un aumento de una desviación estándar (DE) en el IMC aumentabael riesgo de mastitis en un 62,1 % (OR = 1,621, IC 95 % 1,262-2,083, p = 1,59E-4), que es casi consistente con los resultados de otrosdiversos métodos.

Conclusiones:

en los individuos europeos, un aumento del número de IMC aumenta el riesgo de enfermedad inflamatoria mamaria. Las personascon un IMC elevado deben controlar su peso para reducir la incidencia de enfermedad inflamatoria de la mama.(AU)
