Conclusion: There is no relationship between nutritional parenting patterns and the nutritional status of stunted toddlers in Kupang district.

Penguatan Praktik Pemberian Makanan pada Bayi dan Anak (PMBA) Melalui Simulasi dan Demonstrasi Pemberian MP-ASI

West Sulawesi Province is the highest province with stunting above the WHO cut-off (20%), where the incidence of stunting in West Sulawesi is 39.7%. One of the causes of growth and development disorders for babies and children aged 6 to 23 months in Indonesia is the low level of knowledge and practice of providing exclusive breastfeeding, the low quality of complementary feeding. This activity aimed to train and strengthen the practice of giving complementary foods to toddlers by simulating and demonstrating giving complementary foods in accordance with WHO standards. The methods used are counseling, simulation and demonstration of complementary feeding patterns. The target was 30 mothers of toddlers and 5 posyandu cadres. There was an increase in participants' knowledge from 60% to 97% and participants were able to demonstrate the practice of providing MP-ASI based on local food well. It is important to frequently refresh the pattern of giving complementary foods to mothers in groups so that mothers can share knowledge and support each other in practicing the right pattern of giving complementary foods.

An epidemiological study of the determinants and patterns of complementary feeding practices among children of 6-24 months of age group.

The introduction of complementary food is the most important factor determining the nutritional status of the children in the first 2 years of life. This study aimed to find out the determinants and patterns of complementary feeding practices and their impact on the growth and development of children of 6-24 months of age group. Materials and Methods: A descriptive cross-sectional study was done on immunization out patient department (OPD) in the field practice area of the Department of Community Medicine. The sample size taken was 250 using a systematic random sampling method. One hundred and seven (42.8%) were given the optimum amount of complementary food for their age. One hundred and three (41.2%) were fed with an adequate frequency for their age. One hundred and ninety-five (78.0%) were given food that was appropriate in consistency for their age. Among 183 (73.2%) children who were not fed appropriately during and after their illness episodes, 119 (65.0%) were malnourished. On using logistic regression it was seen that the variables which had statistically significant association with the complementary feeding patterns (P<0.05) were maternal education, father's age, total members in the family, advice on complementary feeding from health care workers and use of bottle for feeding. Father's education, availability of ration card, antenatal counselling on childcare, birth order and history of repeated illness in the past did not show statistically significant association with complementary feeding practices (P>0.05). There was no statistically significant difference between the feeding patterns of normal and malnourished children. The association of complementary feeding practices and the anthropometric status of study children was not found statistically significant in the present study. Advice on complementary feeding from healthcare workers is seen to be having a positive impact on complementary feeding practices (P < 0.01).

Adaptive chessboard-like high-frequency projection method for three-dimensional measurement of shiny surfaces

Abstract Shiny surface is challenging for the structured light fringe projection three-dimensional measurement technique, since the image saturation caused by highlight results in incorrect intensities in captured images of fringe patterns, and leads to serious phase errors and measurement errors. To address the issue, an adaptive chessboard-like high-frequency projection intensity adjustment technique is proposed. The proposed method alleviates image saturation by adaptively adjusting the intensity of the high-frequency chessboard-like projection pattern. And the complementary patterns are projected to suppress reflections and enhance the robustness of decoding. The experimental results demonstrate that the proposed method achieve high measurement accuracy for shiny surfaces.

Biogeographic patterns of meio- and micro-eukaryotic communities in dam-induced river-reservoir systems.

Although the Three Gorges Dam (TGD) is the world's largest hydroelectric dam, little is known about the spatial-temporal patterns and community assembly mechanisms of meio- and micro-eukaryotes and its two subtaxa (zooplankton and zoobenthos). This knowledge gap is particularly evident across various habitats and during different water-level periods, primarily arising from the annual regular dam regulation. To address this inquiry, we employed mitochondrial cytochrome c oxidase I (COI) gene-based environmental DNA (eDNA) metabarcoding technology to systematically analyze the biogeographic pattern of the three communities within the Three Gorges Reservoir (TGR). Our findings reveal distinct spatiotemporal characteristics and complementary patterns in the distribution of meio- and micro-eukaryotes. The three communities showed similar biogeographic patterns and assembly processes. Notably, the diversity of these three taxa gradually decreased along the river. Their communities were less shaped by stochastic processes, which gradually decreased along the longitudinal riverine-transition-lacustrine gradient. Hence, deterministic factors, such as seasonality, environmental, and spatial variables, along with species interactions, likely play a pivotal role in shaping these communities. Environmental factors primarily drive seasonal variations in these communities, while hydrological conditions, represented as spatial distance, predominantly influence spatial variations. These three communities followed the distance-decay pattern. In winter, compared to summer, both the decay and species interrelationships are more pronounced. Taken together, this study offers fresh insights into the composition and diversity patterns of meio- and micro-eukaryotes at the spatial-temporal level. It also uncovers the mechanisms behind community assembly in various environmental niches within the dam-induced river-reservoir systems. KEY POINTS: • Distribution and diversity of meio- and micro-eukaryotes exhibit distinct spatiotemporal patterns in the TGR. • Contribution of stochastic processes in community assembly gradually decreases along the river. • Deterministic factors and species interactions shape meio- and micro-eukaryotic community.

Nested graphene disks patterned THz wave absorber: Bio sensing vision

A three-layer adjustable THz wave absorber is introduced in this paper. The structure's geometry is heavily based on a combination of periodic graphene disks and their complementary patterns. Also, the middle layer is considered an air gap while the graphene patterns are stacked into TOPAS filler. Additionally, a golden back reflector is placed at the bottom of the absorber to ensure a blocked transmission channel. This configuration is modeled exclusively by passive circuit elements, while full wave simulation is also performed. Also, a simple genetic-based algorithm is exploited to optimize design parameters in numerical values, including geometrical and stimulation values. In addition, a mechanical tuning setup is suggested that can interestingly change absorption peaks. The frequency shift of absorption peaks can be up to 5 THz, which makes the proposed absorber an ideal basic building block for several applications ranging from sensing to indoor communication. Furthermore, the discussion section explains the potential applications of the proposed absorber for bio-sensing by filling the air gap with biological samples.

Attractive acceptor-acceptor interactions in self-complementary quadruple hydrogen bonds for molecular self-assembly.

Molecular self-assembly provides the means for creating large supramolecular structures, extending beyond the capability of standard chemical synthesis. To harness the power of self-assembly, it is necessary to understand its driving forces. A potent method is to exploit self-complementary hydrogen bonding, where a molecule interacts with its own copy by suitable positions of hydrogen-bond donor (D) and acceptor (A) groups. With four hydrogen bonds, there are two possible self complementary patterns: the DDAA/AADD and the DADA/ADAD motifs. Of these, the DDAA pattern is usually more stable. The traditional explanation assumes that the secondary interactions between equal groups, that is, between donors (D⋯D) or acceptors (A⋯A), are repulsive. DDAA arrays would then have two, and DADA arrays six repulsive interactions. Here, using high-end quantum chemical analysis, we show that contrary to the traditional explanation, the secondary A⋯A interactions are, in fact, attractive. We revise the model of secondary interactions accordingly.

Multi-tracer PET correlation analysis reveals disease-specific patterns in Parkinson’s disease and asymptomatic LRRK2 pathogenic variant carriers compared to healthy controls

Several genetic pathogenic variants increase the risk of Parkinson’s disease (PD) with pathogenic variants in the leucine-rich repeat kinase 2 (LRRK2) gene being among the most common. A joint pattern analysis based on multi-set canonical correlation analysis (MCCA) was utilized to extract PD and LRRK2 pathogenic variant-specific spatial patterns in relation to healthy controls (HCs) from multi-tracer Positron Emission Tomography (PET) data. Spatial patterns were extracted for individual subject cohorts, as well as for pooled subject cohorts, to explore whether complementary spatial patterns of dopaminergic denervation are different in the asymptomatic and symptomatic stages of PD. The MCCA results are also compared to the traditional univariate analysis, which serves as a reference.We identified PD-induced spatial distribution alterations common to DAT and VMAT2 in both asymptomatic LRRK2 pathogenic variant carriers and PD subjects. The inclusion of HCs in the analysis demonstrated that the dominant common PD-induced pattern is related to an overall dopaminergic terminal density denervation, followed by asymmetry and rostro-caudal gradient with deficits in the less affected side still being the best marker of disease progression.The analysis was able to capture a trend towards PD-related patterns in the LRRK2 pathogenic variant carrier cohort with increasing age in line with the known increased risk of this patient cohort to develop PD as they age. The advantage of this method thus resides in its ability to identify not only regional differences in tracer binding between groups, but also common disease-related alterations in the spatial distribution patterns of tracer binding, thus potentially capturing more complex aspects of disease induced alterations.

Toward DNN of LUTs: Learning Efficient Image Restoration with Multiple Look-Up Tables.

The widespread usage of high-definition screens on edge devices stimulates a strong demand for efficient image restoration algorithms. The way of caching deep learning models in a look-up table (LUT) is recently introduced to respond to this demand. However, the size of a single LUT grows exponentially with the increase of its indexing capacity, which restricts its receptive field and thus the performance. To overcome this intrinsic limitation of the single-LUT solution, we propose a universal method to construct multiple LUTs like a neural network, termed MuLUT. Firstly, we devise novel complementary indexing patterns, as well as a general implementation for arbitrary patterns, to construct multiple LUTs in parallel. Secondly, we propose a re-indexing mechanism to enable hierarchical indexing between cascaded LUTs. Finally, we introduce channel indexing to allow cross-channel interaction, enabling LUTs to process color channels jointly. In these principled ways, the total size of MuLUT is linear to its indexing capacity, yielding a practical solution to obtain superior performance with the enlarged receptive field. We examine the advantage of MuLUT on various image restoration tasks, including super-resolution, demosaicing, denoising, and deblocking. MuLUT achieves a significant improvement over the single-LUT solution, e.g., up to 1.1dB PSNR for super-resolution and up to 2.8dB PSNR for grayscale denoising, while preserving its efficiency, which is 100× less in energy cost compared with lightweight deep neural networks. Our code and trained models are publicly available at https://github.com/ddlee-cn/MuLUT.

Complementary Feeding Patterns and Factors Affecting Timely Introduction in a Tribal Population: A Mixed-Methods Study

Introduction: About 29-60% of tribal children are underweight due to limited healthcare access. The Kols, a tribe in central India, face similar issues and our study will examine their complementary feeding practices. Methodology: A sequential explanatory mixed-method research design was conducted on 218 Kol tribe women in the Manikpur block of Chitrakoot district Uttar Pradesh. In the first phase, the quantitative interview using a semi-structured questionnaire and in the second phase, an in-depth interview of 20 Kol mothers was conducted using an interview guide. Results: About 52.3% of the women were aged between 26- 35 years, and about 83.9% were illiterate. About half of the children (n=116, 53.5%) were introduced to complementary feed at 6-8 months of age. The independent predictors of the timely initiation of complementary feeding were education (AOR: 2.422, p 0.037), age of the mothers (AOR: 1.2106, p 0.047) and the number of children of the mothers (AOR: 2.715 p 0.004) diet diversity was rarely maintained. Conclusion: Complementary feed was introduced timely for half of the tribal women but diet diversity was not maintained. Health education and counselling to utilize locally available food items should be encouraged.

LIM-HD transcription factors control axial patterning and specify distinct neuronal and intestinal cell identities in planarians.

Adult planarians can regenerate the gut, eyes and even a functional brain. Proper identity and patterning of the newly formed structures require signals that guide and commit their adult stem cells. During embryogenesis, LIM-homeodomain (LIM-HD) transcription factors act in a combinatorial 'LIM code' to control cell fate determination and differentiation. However, our understanding about the role these genes play during regeneration and homeostasis is limited. Here, we report the full repertoire of LIM-HD genes in Schmidtea mediterranea. We found that lim homeobox (lhx) genes appear expressed in complementary patterns along the cephalic ganglia and digestive system of the planarian, with some of them being co-expressed in the same cell types. We have identified that Smed-islet1, -lhx1/5-1, -lhx2/9-3, -lhx6/8, -lmx1a/b-2 and -lmx1a/b-3 are essential to pattern and size the planarian brain as well as for correct regeneration of specific subpopulations of dopaminergic, serotonergic, GABAergic and cholinergic neurons, while Smed-lhx1/5.2 and -lhx2/9.2 are required for the proper expression of intestinal cell type markers, specifically the goblet subtype. LIM-HD are also involved in controlling axonal pathfinding (lhx6/8), axial patterning (islet1, lhx1/5-1, lmx1a/b-3), head/body proportions (islet2) and stem cell proliferation (lhx3/4, lhx2/9-3, lmx1a/b-2, lmx1a/b-3). Altogether, our results suggest that planarians might present a combinatorial LIM code that controls axial patterning and axonal growing and specifies distinct neuronal and intestinal cell identities.

Gendered stereotype content for people with a nonbinary gender identity

Background Gender stereotypes about women and men have a complementary structure, where women and men are seen as high/low in feminine characteristics and low/high in masculine characteristics. These stereotypes are related to representation within social roles, where beliefs about social role occupation influences which characteristics are associated with women or men. It is not known how people with gender identities that do not fit a binary structure are stereotyped. The current study provides a first step towards addressing this gap. Methods Swedish participants (N = 152) reported descriptive stereotype content (positive/negative feminine/masculine personality characteristics) and estimations of representation within domestic and occupational social roles for people with a nonbinary gender identity for the past, present, and future in a between-groups design. Stereotype content for the past included a higher degree of feminine compared to masculine characteristics, but ratings for the present and future showed no differentiation between femininity and masculinity. Results People with a nonbinary gender identity were believed to more frequently occupy feminine compared to masculine social roles for all time points; this was especially pronounced for occupational social roles. The theorised connection between social role occupation and stereotype content did not emerge: degree of positive masculinity and femininity correlated positively with representation in masculine domestic and occupational roles respectively, but positive femininity was negatively correlated with representation in feminine occupational roles. Conclusions These results indicate that stereotypes about people with a nonbinary gender identity do not show the same complementary pattern or reliance on social roles as gender stereotypes about women and men, but that there is a feminine bias in perceptions of social role occupation for people with a nonbinary gender identity.

Aperture Sharing Metasurface-Based Wide-Beam Antenna for Energy Harvesting

Since the available ambient power level is usually quite low for radio frequency energy harvesting, it is very desirable for an antenna to have both a high gain and a wide beamwidth. Usually, they cannot be achieved simultaneously. In order to overcome this limitation, a multi-port antenna using a nonuniform metasurface (MTS) is presented. In this MTS-based antenna, three modes with complementary radiation patterns are excited through one middle and two side aperture-coupled feeding ports. The first mode is the fundamental TM10 mode with in-phase current distributions on the MTS. It has a broadside directional radiation pattern with a high gain. The second and third modes are symmetrical to each other at a high mode. They have opposite current distributions on two sides of the MTS. These two modes have a directional radiation pattern with a tilted angle. These three modes share the same aperture but are excited by three different feeds. Each feed is connected to a rectifier. By combining direct current (DC) output to a single load, an antenna with a wide beam and a high gain can be effectively achieved, although each mode has the usual limitation of gain and beamwidth. The key advantage of this proposed rectenna is that the unit cells on the MTS layer can be reused to excite different MTS modes with different radiation patterns simultaneously. Thus, a wide beamwidth can be achieved. Three realized beams are oriented at −35°, 0°, and + 35° respectively. By combining the DC output from the three modes, the proposed rectenna has effectively achieved a beamwidth of 114° with a gain ranging from 8 to 9.8 dBi. The RF-to-DC conversion efficiency of the rectifiers is 3%-67% at 2.45 GHz when the input power ranges from −35 to 0 dBm. The proposed MTS antenna with an overall size of λ0 × λ0 × 0.03 λ0 can achieve 12% fractional bandwidth.

Compound climate extremes over the globe during 1951–2021: Changes in risk and driving factors

Compound climate events may include concurrent drought and hot events (compound drought-hot events, CDHEs) or consecutive pluvial and hot events (compound pluvial-hot events, CPHEs). The impacts of compound climate extremes can be reduced by developing adaptation strategies which require reliable monitoring of compound climate events and determining the variability and drivers of their risk. The CDHEs can be characterized by leveraging compound indices, such as Standardized Compound Event Indicator (SCEI), Standardized Dry and Hot Index (SDHI), and Blended Dry and Hot Events Index (BDHI), and the CPHEs can be represented via Blended Pluvial and Hot Events Index (BPHI). When Standardized Precipitation Index (SPI) and Standardized Temperature Index (STI) series are divided into different subseries, based on a specific threshold 0, the dependence paradox occurs, i.e., an opposite dependence is exhibited in comparison of the whole SPI-STI series with the segmented SPI-STI subseries. As BDHI considers the dependence between diverse SPI and STI subseries, it can provide more reliable monitoring for CDHEs than SCEI and SDHI over global land masses during the warm season in the 1951–2021 period. Compared with the period of 1951–1986, the frequency, severity, and spatial extent of CDHEs and CPHEs have exacerbated in the period of 1987–2021 over many regions, e.g., western North America, northern South America, western and central Europe, Africa, and eastern Siberia. The risks of CDHEs and CPHEs are intensified by changes in the SPI-STI dependence and high temperature. Moreover, the contributions of drought and pluvial events (i.e., precipitation changes) to risk variations between CDHEs and CPHEs showed complementary spatial patterns. Our findings emphasize that policymakers and stakeholders need to develop more powerful adaptation strategies to mitigate the intensified risks of compound climate extremes.

Cooperation Mode and Operation Strategy for the Union of Thermal Generating Unit and Battery Storage to Improve AGC Performance

With the growing penetration of intermittent renewable energy resources in power systems, it is a challenge for automatic generation control (AGC) to maintain the required control performance. In recent years, battery energy storage systems (BESSs) have been installed in thermal power plants to provide frequency regulation service bundled with the traditional thermal generating units (TGUs). However, in real projects, the installed BESS typically works as parasitic equipment of the generating unit, which limits the coordination between the TGU and the BESS. In this paper, a complementary cooperation pattern is proposed for the TGU-BESS union to improve the dispatchability of its response to the AGC signal. Then, the correlation between the BESS's energy demand and the TGU's operation states is described by a data-driven method, which combines fuzzy c-means cluster, r-vine copula, and random forest. Finally, a rolling-horizon energy balance strategy is developed to make the control decisions for the TGU-BESS union in response to the stochastic AGC signal. The effectiveness of the proposed method is demonstrated using the historical data from a real union with a 9MW/4.5MWh BESS and a 350MW coal-fired generator.

Bidirectionally Modulating the Dissipative Phase Transition of UCST Polymers in a Programmable Manner Using Visible Light

AbstractDynamic phase transitions are important in living organisms for sustaining their adaptive structures and functions. The design of artificial dynamic systems using light as a noninvasive input fuel has gained significant interest to mimic such adaptive features. Here the development of light‐fueled dissipative phase transitions of upper critical solution temperature polymers by introducing pendant spiropyrans as photoactive units, is reported. The reversible open‐close photoisomerization of spiropyrans is designed to undergo either an enhancement or a decline of their net charge, which is subsequently used to regulate the electrostatic interactions between polymer chains, and ultimately shift their phase transition temperatures to either a lower or a higher direction. The degree and speed of such bidirectional shifting are flexibly modulated by manipulating the external illumination parameters or varying the compositions/concentrations of the polymers. The diametrically opposite transmittance changes driven by light are utilized to produce a series of complementary patterns and shapes for application in transient information storage and encryption with improved accuracy and security. This work offers a bidirectional spatiotemporal modulation of dissipative phase transitions of polymers using visible light that allows highly tunable and adaptable features shared with their natural counterparts.

Sparse Hierarchical Parallel Residual Networks Ensemble for Infrared Image Stream-Based Remaining Useful Life Prediction

Infrared thermography captures real-time degradation temperature information, facilitating non-contact machine health monitoring. However, the inherent multiscale characteristics and spatiotemporal degradation discrepancy in infrared images pose a challenge in learning discriminative degradation features and adaptive prognostic analytics. This paper presents a sparse hierarchical parallel residual networks ensemble (SHPRNE) method to tackle this challenge. First, the hierarchical parallel residual network (HPRN) leverages parallel multiscale kernels to capture complementary degradation patterns separately and embeds a hierarchical residual connection procedure to facilitate the interactivity between coarse-to-fine level features. Moreover, SHPRNE develops a sparse ensemble algorithm integrated with a synergy of network pruning and local minima perpetuation to derive diverse HPRNs while alleviating the parameter storage budget. Pruned HPRNs with varying sparsity and local minima are further integrated into an ensemble learner with higher generalization. Case studies on two infrared image datasets are conducted to demonstrate the effectiveness and superiority of the proposed method.

Emergence of metrically structured rhythms and inter-partner coordination in joint drum improvization

Improvization is a common aspect of music across cultures and eras. Due to its spontaneous nature, it often proves difficult to examine empirically how collective improvization evolves, unless genre-specific constraints are available and followed by experts (e.g., jazz). Here, we investigate the rhythmic dimension of free improvization by non-experts. We focus on two widely used approaches in joint musical improvization: call-and-response (trading) and simultaneous playing (tandem). We hypothesized that non-experts could engage in meaningful joint music-making with a model partner, and that they produce rhythmic patterns with different emergent structures depending on the task. The first author served as a confederate playing with each participant for five blocks each of trading and tandem tasks. To preserve the open-ended nature of improvization, neither metronome nor background music were provided. Preliminary analysis of the rhythmic content indicates that within-player inter-onset-intervals (IOI) reflected a clear hierarchical metrical structure. Additional analysis suggests bi-directional influence between partners in terms of IOI distribution, note density, and timbre choice. During tandem improvization, each partner favored timbres the other did not, showing a complementary pattern. During trading, timbre choice appears more imitative. Subjects also reported an increase in their self-assessed competence and enjoyment of the task over successive blocks.

A double-negative feedback loop between miR319c and JAW-TCPs establishes growth pattern in incipient leaf primordia in Arabidopsis thaliana.

The microRNA miR319 and its target JAW-TCP transcription factors regulate the proliferation-to-differentiation transition of leaf pavement cells in diverse plant species. In young Arabidopsis leaf primordia, JAW-TCPs are detected towards the distal region whereas the major mRNA319-encoding gene MIR319C, is expressed at the base. Little is known about how this complementary expression pattern of MIR319C and JAW-TCPs is generated. Here, we show that MIR319C is initially expressed uniformly throughout the incipient primordia and is later abruptly down-regulated at the distal region, with concomitant distal appearance of JAW-TCPs, when leaves grow to ~100 μm long. Loss of JAW-TCPs causes distal extension of the MIR319C expression domain, whereas ectopic TCP activity restricts MIR319C more proximally. JAW-TCPs are recruited to and are capable of depositing histone H3K27me3 repressive marks on the MIR319C chromatin. JAW-TCPs fail to repress MIR319C in transgenic seedlings where the TCP-binding cis-elements on MIR319C are mutated, causing miR319 gain-of-function-like phenotype in the embryonic leaves. Based on these results, we propose a model for growth patterning in leaf primordia wherein MIR319C and JAW-TCPs repress each other and divide the uniformly growing primordia into distal differentiation zone and proximal proliferation domain.

Minimum acceptable diet in a cohort of children aged between 6 and 15 months: Complementary feeding assessment and associated factors in the Brazilian western Amazon

ObjectiveThe goal of the article was to assess complementary feeding patterns, and associated factors, of children between 6 and 15-month old in Rio Branco-Acre, Brazil, based on the minimum acceptable diet indicator. MethodsThis study was cross-sectional, including 857 children between ages 6 and 15 mo, from a 2015 birth cohort of Rio Branco, Brazil. The prevalence of complementary feeding indicators, minimum meal frequency, minimum dietary diversity, and minimum acceptable diet was estimated based on the recommendations of the World Health Organization. Sociodemographic characteristics, infant and maternal habits, prenatal information, birth characteristics, breastfeeding, and complementary feeding were evaluated. Differences between the proportions were evaluated by the χ2 test and univariate and multiple logistic regression analyses, to determine associated factors with child minimum acceptable diet. ResultsThe minimum frequencies of meals and dietary diversity were observed in 81.0% and 51.8% of the children, respectively. The minimum acceptable diet prevalence was 47.1%. Also, minimum acceptable diet was inversely associated with C, D, and E social classes (adjusted odds ratio = 0.49; 95% CI, 0.33–0.72), number of living siblings (adjusted odds ratio for two or three children = 0.69; 95% CI, 0.48–0.98, and adjusted odds ratio for ≥ 4 children = 0.56; 95% CI, 0.37–0.84). Maternal regular consumption of fruits, vegetables, and legumes (adjusted odds ratio = 2.62; 95% CI, 1.69–4.05), child age from 12 to 15 mo (adjusted odds ratio = 2.05; 95% CI, 1.32–3.18), and receiving guidance regarding complementary feeding during postnatal consultations (adjusted odds ratio = 1.38; 95% CI, 1.03–1.86) were directly associated with minimum acceptable diet. ConclusionsFewer than 50% of the children received adequate food with adequate frequency and diversity. Low socioeconomic status and having ≥ 2 living siblings reduced the chance of minimum acceptable diet, whereas maternal healthy diet, child age (12–15 mo), and complementary feeding counseling during postnatal appointments increased the chance of minimum acceptable diet.
