Time living with food insecurity and socio-demographic factors: longitudinal analysis in a city in the semi-arid region of Northeast Brazil.

OBJECTIVE: Food insecurity (FI) is the lack of daily access for everyone to quality food in sufficient quantity. In many populations, it presents as a chronic and persistent condition. This study analysed the association between the length of time living with FI and socio-demographic conditions in households in a semi-arid municipality in the Brazilian Northeast between 2011 and 2019. DESIGN: This is a population-based cohort study among families in the municipality in Northeast Brazil (2011, 2014 and 2019). FI was estimated through the Escala Brasileira de Insegurança Alimentar (EBIA, Brazilian Household Food Insecurity Measurement Scale), and the longitudinal category of time of living with FI was adopted to classify them according to the time they remained in FI during the cohort. The association with the socio-demographic profiles of the population was verified through multinomial logistic regression. SETTING: Households in semi-arid, Northeast of Brazil. PARTICIPANTS: Household respondents interviewed in 2011, 2014 and 2019 (n 274). RESULTS: Sixty-seven percentage (67 %) of families lived in FI in this period. Rural residence, low monthly per capita income and low schooling of the household reference person increased the chances of these families living longer in FI. These overlapping conditions increased the odds of FI in the household. CONCLUSIONS: Coping with FI requires intersectoral intervention that improves the socio-demographic conditions of the population.

Impact of 0.12% Chlorhexidine Gluconate Mouthwash on Peri-Implant Mucositis and Gingivitis After Nonsurgical Treatment: A Multilevel Analysis.

PURPOSE: This study investigated the impact of 0.12% chlorhexidine gluconate mouthwash on dental implants with periimplant mucositis and contralateral teeth with gingivitis at 6 months of follow-up after nonsurgical treatment. MATERIALS AND METHODS: This was a secondary analysis of data from a previous controlled, randomized, double-blinded clinical trial of 30 patients diagnosed with peri-implant mucositis and gingivitis in contralateral teeth, at 6 months following treatment. Patients were randomly assigned into a test group (basic periodontal therapy + 0.12% chlorhexidine mouthwash) or a control group (basic periodontal therapy + placebo). Therapy consisted of an adaptation of the full-mouth scaling and root planing protocol. The clinical parameters of visible Plaque Index, Gingival Bleeding Index, probing depth, bleeding on probing, keratinized mucosa width, and gingival and peri-implant phenotype were evaluated at baseline and at 1, 3, and 6 months posttherapy. Data were analyzed using Poisson multilevel regression analysis with a significance level of .05. RESULTS: The study analyzed 47 implants and contralateral teeth (376 sites) in the test group and 49 implants and contralateral teeth (392 sites) in the control group. No differences were found between the groups at the patient level. At the site level, the teeth and implants presented statistical differences in bleeding on probing, probing depth, and keratinized mucosa width at 3 months for both treatment groups. However, no difference was observed in bleeding on probing in the test group (P = .484) at 6 months, whereas the control group demonstrated increased bleeding on probing (indicating more inflammation) at implant sites than at teeth sites (P = .039). Additionally, implant sites with a thin peri-implant phenotype (P < .001) and located posteriorly (P = .002) presented greater inflammation. CONCLUSION: Use of a 0.12% chlorhexidine mouthwash for 14 days was beneficial for implant sites with peri-implant mucositis, compared to contralateral teeth sites with gingivitis, as indicated by the reduced percentage of teeth with bleeding on probing.
